New syntheses of tandospirone have been described: 1) The hydrogenation of bicyclo[2.2.1]hept-5-ene-2,3-di-exo-carboxylic acid anhydride (I) with H2 over Pd/C in THF-water gives bicyclo[2.2.1]heptane-2,3-di-exo-carboxylic acid anhydride (II), which by reaction with ammonia in THF-water is converted into the imide (III). The reaction of (III) with 1,4-dibromobutane by means of K2CO3 in refluxing acetone yields N-(4-bromobutyl)bicyclo[2.2.1]heptane-2,3-di-exo-carboximide (IV), which is finally condensed with 1-(2-pyrimidinyl)piperazine (V) by means of K2CO3 and KI in hot DMF. 2) Imide (III) is condensed with propargyl bromide (VI) by means of K2CO3 in refluxing acetone affording N-propargylbicyclo[2.2.1]heptane-2,3-di-exo-carboximide (VII), which is allowed to react with piperazine (V) and formaldehyde by means of CuSO4 in dioxane to give N-[4-[4-(2-pyrimidinyl)piperazin-1-yl]-2-butynyl]bicyclo[2.2.1]heptane-2,3-di-exo-carboximide (VIII). Finally, this compound is reduced with H2 over Pd/C. 3) The condensation of piperazine (V) with 4-chlorobutyronitrile (IX) by means of NaOH in acetone gives 4-[4-(2-pyrimidinyl)piperazin-1-yl]butyronitrile (X), which is reduced with LiAlH4 in ether yielding 1-(4-aminobutyl)-4-(2-pyrimidinyl)piperazine (XI).

The synthesis of tritiated cabergoline by two similar routes has been described: 1) The acylation of 6-nor-dihydrolysergic acid methyl ester (I) with propargyl bromide yields the corresponding 6-propargyl derivative (II), which is hydrogenated with tritium gas over Pd/C in the presence of quinoline to give the ditritiated 6-allyl derivative (III). This compound is treated with 3-(dimethylamino)propylamine at 120 C, yielding the amide (IV), which is finally treated with ethyl isocyanate. 2) The reaction of the propargyl derivative (II) with 3-(dimethylamino)propylamine as before gives the amide (V). The reaction of (V) with ethyl isocyanate gives compound (VI), which is then hydrogenated with tritium as before.

Michael addition of acrylonitrile (II) to 2-methyl-3-aminopropionitrile (I) gave dinitrile (III), which was cyclized to piperidone (IV) under Thorpe-Ziegler conditions. After protection of (IV) as the carbamate (V), hydrolysis of the nitrile with 85% H2SO4 provided ketoamide (VI). This was converted to enamine (VII) by condensation with benzylamine in refluxing xylene. Subsequent treatment of (VII) with H2S in DMF, followed by bromine in AcOH furnished isothiazole (VIII). The ethoxycarbonyl group of (VIII) was then replaced for a tert-butoxycarbonyl group by hydrolysis with HBr in AcOH to (IX), and then reaction with Boc2O to give a N,O-di-Boc intermediate, which was further treated with K2CO3 in MeOH to afford (X). After alkylation of the hydroxyl group of (X) with propargyl bromide (XI), the tert-butyl carbamate was removed with ethereal HCl to yield the racemic isothiazolopyridine (XII). Finally, the (S)-(+)-enantiomer of (XII) was resolved by crystallization as the diastereomeric salt with D-(+)-dibenzoyltartaric acid and, after liberation of the base with NaOH, was isolated as the fumarate salt.

The reaction of indan-5-amine (I) with acetic anhydride gives the acetamide (II), which is brominated with Br2 in acetic acid yielding the 6-bromo derivative (III). The reaction of (III) with CuCN in 1-methyl-2-pyrrolidone at 125 C affords the corresponding nitrile (IV), which is cyclized by means of H2O2 and NaOH in hot ethanol/water giving the tricyclic ketone (V). The reaction of (V) with chloromethyl pivalate (A) and potassium tert-butoxide in DMSO yields the pivaloyloxymethyl derivative (VI), which is oxidized with CrO3 and tert-butyl peroxide in dichloromethane affording the diketone (VII) (after chromatographic separation of the undesired regioisomer). The condensation of (VII) with N-(4-aminobenzoyl)-Lglutamic acid diethyl ester (VIII) by means of TsOH in refluxing DME gives the imino derivative (IX), which without isolation, is reduced to the secondary amine (X) (as a diastereomeric mixture) with NaBH3CN in methanol/acetic acid. The alkylation of the secondary amine group of (X) with propargyl bromide (XI) and CaCO3 in hot DMA yields the tertiary amine (XII), which is hydrolyzed and deprotected with first with NaOH in methanol/water, and then with aqueous HCl to provide the target compound as a diastereomeric mixture. Finally, this compound is resolved by a treatment with carboxypeptidase G2 and ZnCl2 in water that hydrolyzes selectively the undesired isomer.

Alkylation of methyl 4-(acetylamino)-2-hydroxybenzoate (I) with propargyl bromide (II) in the presence of K2CO3 in refluxing acetonitrile gave propargyl ether (III), and subsequent chlorination with N-chlorosuccinimide in DMF yielded (IV). Then, a Claisen-type rearrangement of (IV) in boiling diphenyl ether furnished the benzopyran (V), which was hydrogenated over Pt/C to give dihydrobenzopyran (VI). Subsequent treatment of (VI) with 4 N KOH produced the hydrolysis of both ester and amide functions, affording acid (VII). Treatment of dicyclopropyl ketone (VIII) with HCl gas provided 1,7-dichloro-4-heptanone (IX). Cyclization of (IX) with cyanoacetic acid in a two-phase system of aqueous ammonia and n-hexane gave bicyclic intermediate (X), which upon decarboxylation yielded nitrile (XI). Subsequent hydrogenation in the presence of Raney-Ni and NaOH furnished 5-(2-aminoethyl)-1-azabicyclo[3.3.0]octane (XII) (3). The title compound was then obtained by coupling of acid (VII) with amine (XII) using carbonyldiimidazole (CDI), followed by conversion to the hemifumarate salt.

The protected acid chloride (X) was prepared by several methods. Alkylation of 4-mercaptophenol (I) with propargyl bromide (II) gave thioether (III). The phenolic hydroxyl of (III) was subsequently protected as the sulfonate ester (IV) by treatment with benzenesulfonyl chloride. The sulfide group of (IV) was then oxidized to the sulfoxide (V) by means of in situ generated performic acid. Rearrangement of the propargyl sulfoxide (V) in refluxing DME gave rise to the 3-(hydroxymethyl)benzothiophene (VI). Oxidation of alcohol (VI) to the corresponding aldehyde (VII) by means of NaOCl in the presence of TEMPO, followed by oxidation with sodium chlorite, furnished the carboxylic acid (VIII). Alternatively, the sulfonate acid (VIII) was obtained by acylation of the known 5-hydroxybenzothiophene-3-carboxylic acid (IX) with benzenesulfonyl chloride. Conversion of acid (VIII) into acid chloride (X) was effected by chlorination with SOCl2 in the presence of a catalytic amount of DMF.

N-Protection of (VI) is then performed by treatment with di-t-butyl dicarbonate and Et3N in THF to furnish Boc derivative (VII), which is then converted into derivative (IX) by O-acylation with N-Me, N-Et carbamoyl chloride (VIII) by means of NaH in acetonitrile. Removal of the Boc group of (IX) by treatment with HCl (gas) in dioxane gives hydrochloride (X), which is finally N-alkylated with propargyl bromide (XI) by means of K2CO3 in acetonitrile to yield the desired product.

Ketoester (II) was prepared by condensation of dimethyl carbonate with 5-methoxy-2-tetralone (I) in the presence of NaOMe. The alkylation of (II) with allyl bromide using two equivalents of LDA at -78 C proceeded selectively on the C-3 position to give (III). Further decarbomethoxylation of (III) was carried out with LiCl in moist DMSO at high temperature, and the resulting ketone (IV) was converted to ethylene ketal (V) with ethylene glycol and p-TsOH. Then, hydroboration of (V) with disiamyl borane (VI) in cold THF, followed by oxidation of borane (VII) with H2O2-NaOH furnished the primary alcohol (VIII). After Jones oxidation of alcohol (VIII), the resulting acid (IX) was esterified with MeOH and H2SO4 to give ketoester (X). Subsequent cyclization of (X) with benzylamine (XI) and AcOH in refluxing benzene afforded the intermediate tricyclic enamide (XII), which was sequentially reduced with LiAlH4 to enamine (XIII), and then with NaBH4 in the presence of AcOH to furnish a mixture of cis and trans octahydrobenzo[g]quinolines (XIV). Separation of the major trans isomer by flash chromatography was followed by hydrogenolysis of the benzyl group over Pd/C, yielding the secondary amine (XV), whitch was N-alkylated with propargyl bromide (XVI) in hot DMF to give (XVII).

This compound has been obtained by two related ways: The demethylation of levorphanol (I) by the deGraw and Engstrom procedure (ethyl chloroformate and K2CO3 in refluxing chloroform and hydrolysis with NaOH) gives norlevorphanol (II), which is alkylated with propargyl bromide (III) and K2CO3 in hot DMF to yield the N-propargyl derivative (IV). The hydrostannylation of (IV) with HSnBu3 and Et3B in THF affords a mixture of the trans-(V) and cis-(VI) tributyltin precursors that are separated by column chromatography. Finally, the desired trans-isomer (V) is iodinated with I2 in CHCl3 to provide the target iodoallyl morphinan derivative. Alternatively, the hydrostannylation of propargyl alcohol (VI) by conventional methods gives the (E)-3-(tributylastannyl)allyl alcohol (VII), which is treated with CCl4 and PPh3 to yield the corresponding allyl bromide (VIII). Finally, the N-alkylation of norlevorphanol (II) with the allyl bromide (VIII) affords the already reported trans-(tributylstannyl)precursor (V).

From the intermediate morpholine (XVIII) the title compound was obtained by several routes. Alkylation of (XVIII) with propargyl bromide (XXXI) gave the N-propargyl morpholine (XXXII). Palladium-catalyzed addition of N,N-dimethylcarbamoyl chloride to the propargyl group of (XXXII) produced the butynamide derivative (XXXIII). The target triazole system (XXXIV) was obtained by dipolar cycloaddition of NaN3 to the acetylenic triple bond of (XXXIII) in hot DMSO. Finally, amide reduction in (XXXIV) with LiAlH4 led to the title dimethylaminomethyl triazole, which was isolated as the hydrochloride salt.

The title ketolide was synthesized starting from 2',4''-bis-O-trimethylsilylerythromycin A 9-O-(1-isopropoxycyclohexyl)oxime (I). Selective alkylation of (I) at the 6-hydroxyl group with propargyl bromide (II) furnished the propargyl ether (III). Then, acidic hydrolysis of the oxime ketal and the silyl ether groups of (III) provided (IV). Conversion of oxime (IV) into the corresponding ketone (V) was accomplished via diazotization with NaNO2 and HCl. The 2' and 4'' hydroxyl groups of (V) were then protected by esterification with acetic anhydride and DMAP to afford diacetate (VI). Treatment of (VI) with carbonyldiimidazole and NaH caused the elimination of the 11-hydroxyl group and formation of the 12-O-imidazolide (VII).

N-Demethylation of cocaine (I) is accomplished by treatment with 1-chloroethyl chloroformate, followed by methanolysis of the intermediate chloroethyl carbamate. The resultant nor-cocaine (II) is alkylated with propargyl bromide (III) to afford (IV). Acidic ester hydrolysis of (IV) furnishes hydroxy acid (V). Chlorination of (V) with POCl3, followed by treatment with methanol gives rise to the unsaturated ester (VI). Radical cyclization of the enyne system (VI) in the presence of Bu3SnH and AIBN affords a Z/E mixture of tricyclic vinyl stannanes (VIIa-b) that are separated by column chromatography. The major Z isomer is then subjected to Stille coupling with the aryl iodide (VIII), yielding adduct (IX). Then, reduction of the ester function of (IX) to the primary alcohol (X) is performed by means of either LiAlH4 or DIBAL.
