The copolymerization of ethylene (III) and maleic anhydride (II) in ethylbenzene (I) by means of benzoyl peroxide (IV) at 70 C gives an ethylene/maleic anhydride copolymer (V), which is ammoniated by treating with liquid ammonia in acetone yielding the ammoniated ethylene/maleic acid copolymer (VI). Finally, this product is imidated partially by heating in refluxing xylene.

The cyclization of trifluoroacetylmethylpyridinium bromide (I) with 3-(4-trifluoromethylbenzoyl)acrylic acid (II) by means of ammonium acetate in refluxing methanol gives 2-trifluoromethyl-6-(4-trifluoromethylphenyl)isonicotinic acid (III), which by condensation with 2-bromopyridine (IV) by means of butyllithium in ethyl ether yields 2-trifluoromethyl-6-(4-trifluoromethylphenyl)4-pyridyl-2'-pyridyl ketone (V). Finally, this compound is reduced with H2 over Pt in aqueous concentrated HCl. The starting products are prepared as follows: 1) The acrylic acid (II) is obtained by condensation of maleic anhydride (VI) with 4-trifluoromethylphenylmagnesium bromide (VII) by means of ZnCl2 in refluxing ethyl ether. An alternative method is the condensation of 4-trifluoromethylacetophenone (VIII) with glyoxylic acid (IX) by means of triethylamine at 135 C. 2) The pyridinium salt (I) is prepared by bromination of 1,1,1-trifluoroacetone (X) giving 1,1,1-trifluoro-3-bromoacetone (XI), which is then condensed with pyridine.

An asymmetric synthesis of (-)-quinocarcin has been described: The acylation of 2-(2-methoxy-6-methylphenyl)-(R)- glycinol (I) with maleic anhydride (II) in ether gives the maleic monoamide (III), which is cyclized to the pyrrolidinedione (IV) by refluxing with acetic anhydride. The cyclization of (IV) with methyl azide in toluene affords the pyrrolotriazole (V), which is irradiated with UV light (Hg lamp), giving the aziridinopyrrole (VI). The cycloaddition of (VI) with the chiral acrylamide (VII) affords the diazabicyclo[3.2.1]octane (VIII). At this point, the hydroxyl group of (VIII) is protected with methoxymethyl chloride giving the methoxymethyl ether (IX), which is submitted to benzylic bromination with N-bromosuccinimide (NBS) in chloroform, yielding the bromo derivative (X). The reaction of (X) with triphenylphosphine affords the phosphonium salt (XI), which by treatment with potassium tert-butoxide and heat cyclizes to the tetracyclo compound (XII). Hydrogenation of (XII) with H2 over RaNi in ethanol affords the reduced compound (XIII), which is treated with LiOH in THF - water, affording the free acid derivative (XIV). The deprotection of the ether group of (XIV) with trimethylsilyl chloride and NaI in acetonitrile gives the hydroxymethyl derivative (XV), which is finally cyclized to (-)-quinocarcin with AgNO3 in methanol-water.

The synthesis of SM-3997 labeled in the carbonyl groups or the pyrimidine ring has been reported: The Diels-Alder condensation of cyclopentadiene (II) with [14C]-labeled maleic anhydride (I) gives bicyclo[2.2.1]hept-5-ene-2,3-endo-di[14C]-carboxylic anhydride (III), which by treatment with ammonia in THF is converted to the corresponding imide (IV endo). Heating of (IV endo) at 190 C in diphenylether affords the corresponding exo isomer (IV exo), which is hydrogenated with H2 over Pd/C in ethanol - THF to give the saturated exo-imide (V). The condensation of (V) with 1,4-dibromobutane (VI) by means of K2CO3 in refluxing acetone yields the N-(4-bromobutyl)imide (VII), which is finally condensed with 1-(2-pyrimidinyl)piperazine (VIII) by means of K2CO3 and KI in hot DMF to afford SM-399 [14C]-labeled at the carbonyl groups.

The Diels-Alder condensation of maleic anhydride (I) with furan (II) gives the epoxytetrahydrophthalic anhydride (III), which is reduced with H2 over Pd/C, yielding the epoxyperhydrophthalic anhydride (IV). Further reduction of (IV) with NaBH4 affords the epoxyperhydrophthalide (V), which is submitted to a third reduction with DIBAL-H to provide the lactol (VI) as a racemic mixture that is resolved with menthol. The appropriate isomer (VIIa) is treated with triphenylphosphonium bromide (VIII) and potassium tert-amyloxide to give the 5,8-epoxyperhydro-2-benzopyran-3-ol (IX), which is condensed with 4-carboxybutyltriphenylphosphonium bromide (X) by means of potassium tert-amyloxide and esterified with Amberlist-15/MeOH, yielding the cis-5-heptenoic acid methyl ester (XI). The oxidation of the primary alcohol group of (XI) with pyridinium chlorochromate (PCC) in dichloromethane affords the aldehyde (XII), which is finally reductocondensed with 4-phenylsemicarbazide (XIII) by means of NaBH3CN and hydrolyzed with LiOH to furnish the target semicarbazide.

Reaction of 1,3,5,7-cyclooctatetraene (I) with maleimide (Step a, b), or maleic anhydride (Step c), in refluxing toluene affords the imide (II) or the anhydride (III) in 78 and 85% yields, respectively. Reaction of imide intermediate (II) with 1,4-dibromobutane gives the omega-haloalkylimide, which subsequently is reacted with 1-(2-pyrimidinyl)piperazine to yield Wy-47846 (Method A). Alternatively, Wy-47846 can be prepared via the reaction of (III) with 1-(4-aminobutyl)-4-(2-pyrimidinyl)piperazine in refluxing pyridine (Method B), as shown in scheme. Wy-47846 is achiral.

The Diels-Alder condensation of maleic anhydride (I) with furan (II) gives the epoxytetrahydrophthalic anhydride (III), which is reduced with H2 over Pd/C, yielding the epoxyperhydrophthalic anhydride (IV). Further reduction of (IV) with NaBH4 affords the epoxyperhydrophthalide (V), which is submitted to a third reduction with DIBAL-H to provide the lactol (VI) as a racemic mixture that is resolved with menthol. The appropriate isomer (VIIa) is treated with triphenylphosphonium bromide (VIII) and potassium tert-amyloxide to give the 5,8-epoxyperhydro-2-benzopyran-3-ol (IX), which is condensed with 4-carboxybutyltriphenylphosphonium bromide (X) by means of potassium tert-amyloxide and esterified with Amberlist-15/MeOH, yielding the cis-5-heptenoic acid methyl ester (XI). The sulfonation of the primary alcohol group of (XI) with TsOH affords the tosylate (XII), which is condensed with potassium phthalimide (XII) to provide the phthalimido derivative (XIV). The treatment of (XIV) with hydrazine gives the aminomethyl compound (XV), which is finally condensed with N-(heptanoyl)glycine (XVI) by means of CDI and hydrolyzed with LiOH to afford the target glycinamide compound.

The condensation of indane-1,3-dione (I) with benzaldehyde (II) by means of piperidine in refluxing benzene gives 2-benzylideneindane-1,3-dione (III), which is treated with H2O2 and NaOH in methanol to yield the epoxide (IV). The condensation of (IV) with N-(3,4-dichlorophenyl)maleimide (V) (obtained by condensation of 3,4-dichloroaniline (VI) with maleic anhydride (VII) in diethyl ether) in refluxing benzene affords a mixture of two diastereomeric racemates from which the desired isomer (VIII) is separated by column chromatography (1-3). Finally, (VIII) is reduced with NaBH4 in methanol to provide a diastereomeric mixture from which the title product is separated by chromatography.

6-Aminocaproic acid (I) is condensed with maleic anhydride (II) in refluxing AcOH to provide maleimidocaproic acid (III). After activation of acid (III) as the corresponding mixed anhydride with isobutyl chloroformate, coupling with tert-butyl carbazate (IV) affords the N-Boc hydrazide (V). Subsequent acidic cleavage of the Boc group of (V) furnishes hydrazide (VI). Finally, hydrazide (VI) is condensed with doxorubicin (VII) to produce the title hydrazone conjugate.
