(V) By cyclization of 3-nitrobenzaldehyde (I) with 3-nitratopropyl-3-aminocrotonate (II) and 2-nitratopropyl acetoacetate (III) in refluxing benzene. The starting products (II) and (III) are obtained as follows:
The reaction of diketene (IV) with 3-bromopropanol (V) by means of sodium acetate at 50 C gives 3-bromopropyl acetoacetate (VI), which by reaction with AgNO3 in refluxing acetonitrile is converted to 3-nitratopropyl acetoacetate (VII). Finally, this compound is treated with NH3 in THF to afford the aminocrotonic ester (II).
The reaction of diketene (IV) with 2-chloropropanol (VIII) as before gives 2-chloropropyl acetoacetate (IX), which is treated with AgNO3 as before to yield acetoacetate (III).

(XVI) 5) The cyclization of D-penicillamine (X) with 2-methoxybenzaldehyde (XI) in ethanol gives (4S)-2-(2-methoxyphenyl)-5,5-dimethylthiazolidine-4-carboxylic acid (XII), which by acetylation with hot acetic anhydride and fractional crystallization yields the chiral (2S,4S)-3-acetyl-2-(2-methoxyphenyl)-5,5-dimethylthiazolidine-4-carboxylic acid (XIII). The esterification of (XIII) with the hydroxyl group of benzothiazinone (I) by means of dicyclohexylcarbodiimide (DCC) and dimethylaminopyridine (DMAP) in DMF affords a diastereomeric mixture of esters, which is separated by fractional crystallization giving ester (XIV). Elimination of the chiral auxiliar by treatment with calcium borohydride in THF or sodium borohydride in ethanol (2) gives (R)-2-(2-hydroxy-5-methoxyphenyl)-4-methyl-3,4-dihydro-2H-1,4-benzothiazin-3-one (XV), which is condensed with 3-bromopropanol (XVI) by means of triphenylphosphine and diethyl azodicarboxylate in DMF or THF yielding (R)-2-[2-(3-bromopropoxy)-5-methoxyphenyl]-4-methyl-3,4-dihydro-2H-1,4-benzothiazin-3-one (XVII). Finally, this compound is condensed with the secondary amine (IV) by means of NaI and NaHCO3 as already described, and treated with fumaric acid as before.

(XXI) In a related synthesis, (3,4-dichlorophenyl)acetonitrile (XI) was alkylated with bromide (XXII) --prepared by protection of 3-bromopropanol (XXI) with dihydropyran-- to afford (XXIII). Subsequent Michael addition of methyl acrylate (XII) to (XXIII) in the presence of Triton B® gave the cyanoacid (XXIV). This was cyclized to the glutarimide (XXV) by refluxing in HOAc in the presence of H2SO4. Reduction of (XXV) using borane-dimethylsulfide complex produced the already reported racemic piperidinoalcohol (XVI). After acylation of the amine group of (XVI) with benzoyl chloride to yield (XXVI), its hydroxyl group was converted into the target mesylate precursor (XXVII) with methanesulfonyl chloride and Et3N.

(IV) The cyclization of 2-methylphenyl isothiocyanate (I) with 2-aminoacetaldehyde dimethylacetal (II) in methanol gives the 1-(2-methylphenyl)imidazole-2-thiol (III), which is condensed with 3-bromopropanol (IV) by means of NaOH in refluxing water to yield the sulfide (V). The asymmetric oxidation of sulfide (V) with Ti(O-iPr)4, cumene hydroperoxide (CHP) and (R)-(-)-mandelic acid as chiral catalyst in dichloromethane affords the (S)-sulfinyl derivative (VI), which is treated with Ms-Cl to provide the expected mesylate (VII). Finally, this compound is condensed with the sodium salt of 6-hydroxy-1,2,3,4-tetrahydroquinolin-2one (VIII) to give the target compound.

Alkylation of isonipecotamide (I) with n-butyl bromide in the presence of potassium carbonate gives the amide (II), which is reduced with lithium aluminum hydride to afford 1-butyl-4-piperidinylmethylamine (III). Conversion of indole-3-carboxylic acid (IV) to the acid chloride (V) is carried out with oxalyl chloride in dichloromethane containing N,N-dimethylformamide (DMF). Coupling of the amine (III) with the acid chloride (V) in dichloromethane in the presence of triethylamine gives N-[(1-butyl-4-piperidinyl)methyl]indole-3-carboxamide (VI). N-[(1-butyl-4-piperidinyl)methyl]-3,4-dihydro-2H-[1,3]-oxazino[3,2-a] indole-10-carboxamide (VIII) is formed by treatment of the amide (VI) with N-chlorosuccinimide in chloroform followed by reaction with 3-bromopropanol and cyclization of the intermediate ether (VII) with potassium carbonate in acetone. Conversion to N-[(1-butyl-4-piperidinyl)methyl]-3,4-dihydro-2H-[1,3]oxazino[3,2-a] indole-10-carboxamide hydrochloride (SB-207266) is effected by treatment of (VIII) with anhydrous HCl in ethanol.

Reaction of vanillic acid (I) with 3-bromopropanol gave ether (II). Subsequent nitration of (II) with simultaneous oxidation of the primary alcohol employing nitric acid afforded the nitro diacid (IV), which by chemoselective esterification in the presence of a catalytic amount of p-toluenesulfonic acid yielded monoester (IV). After conversion of (IV) to the acid chloride upon treatment with oxalyl chloride, coupling with (S)-2-(hydroxymethyl)pyrrolidine (V) gave amide (VI). Catalytic hydrogenation of the nitro group of (VI), followed by protection of the intermediate aniline with 2,2,2-trichloroethyl chloroformate provided carbamate (VII). Further Swern oxidation of the alcohol group of (VII) with concomitant cyclization generated the pyrrolobenzodiazepine (VIII). The methyl ester of (VIII) was then hydrolyzed to carboxylic acid (IX).

The intermediate 5,5'-carbonylbis(3-chloro-2-methoxybenzoic acid methyl ester) (X) has been obtained as follows: The dimerization of 3-chloro-2-hydroxybenzoic acid (XII) with H2CO and H2SO4 in methanol gives 5,5'-methylenebis(3-chloro-2-hydroxybenzoic acid) (XIII), which is fully methylated with SO4Me2 or CO3Me2 and K2CO3 yielding 5,5'-methylenebis(3-chloro-2-methoxybenzoic acid methyl ester) (XIV). Finally, this compound is oxidized with CrO3 in acetic anhydride to afford the desired intermediate (X).

(I) The reaction of 3-bromopropanol (I) with TBDMS-Cl, DIEA and DMAP in dichloromethane gives the silyl ether (II), which is treated with PPh3 in refluxing acetonitrile yielding the phosphonium salt (III). The Wittig reaction of (III) with 3-cholestanone (IV) by means of BuLi in DME affords 3-[3-(tert-butyldimethylsilyloxy)propylidene]cholestane (V), which is reduced with H2 over PtO2 in ethyl acetate giving 3beta-[3-(tert-butyldimethylsilyloxy)propyl]cholestane (VI). The reaction of (VI) with TBAF in THF gives the 3-hydroxypropyl derivative (VII), which is treated with CBr4 and PPh3 in dichloromethane yielding the 3-bromopropyl derivative (VIII). The reaction of (VIII) with PPh3 in refluxing chlorobenzene affords the phosphonium salt (IX), which is submitted to a Wittig condensation with 5,5'-carbonylbis(3-chloro-2-methoxybenzoic acid methyl ester) (X) by means of NaN(SiMe3)2 in THF giving the expected condensation intermediate (XI).
The intermediate 5,5'-carbonylbis(3-chloro-2-methoxybenzoic acid methyl ester) (X) has been obtained as follows: The dimerization of 3-chloro-2-hydroxybenzoic acid (XII) with H2CO and H2SO4 in methanol gives 5,5'-methylenebis(3-chloro-2-hydroxybenzoic acid) (XIII), which is fully methylated with SO4Me2 or CO3Me2 and K2CO3 yielding 5,5'-methylenebis(3-chloro-2-methoxy-benzoic acid methyl ester) (XIV). Finally, this compound is oxidized with CrO3 in acetic anhydride to afford the desired intermediate (X).

(A) Acetonitrile derivative (I) is treated with BuLi and alkylated with 3-bromopropanol (A) to yield alcohol (II), which is further alkylated by means of LICKOR (n-BuLi/t-BuOK) and 1-chloro-3-bromopropane (B) to afford (III). Reaction of derivative (III) with secondary amine (VIII) in acetonitrile gives (IV). Amine (VIII) is obtained by trifluoroacetylation of azide (VI) with trifluoroacetic anhydride to yield (VII), which is then N-methylated by means of MeI and hydrolyzed with KOH. Finally, alcohol (IV) reacts with succinimido biotinate (V) in DMSO to provide the desired product.

(IV) The title compound was prepared by solid-phase synthesis on a Sasrin resin. The silylated m-hydroxyphenylacetic acid (I) was attached to the resin using DCC and DMAP to yield the acid-bound resin (II). The silyl group of (II) was then removed by treatment of resin (II) with tetrabutylammonium fluoride in THF. The resultant phenol (III) was coupled to 3-bromo-1-propanol (IV) under Mitsunobu conditions to afford the bromide functionalized resin (V). Displacement of the bromide ion of (V) with 2,2-diphenylethylamine (VI) furnished the secondary amine (VII), which was subjected to reductive alkylation with aldehyde (VIII) in the presence of NaBH(OAc)3 to produce the resin-bound product (IX). Cleavage from the solid support employing trifluoroacetic acid in CH2Cl2 provided the target carboxylic acid.
