Abstract: A process for the preparation of vincadifformine and related derivatives which are useful as starting material for the synthesis of, among other alkaloids, vincamine and other similar compounds possessing interesting psychopharmacologic properties. A tetrahydro- beta -carboline (II) is reacted with benzoyl chloride to provide a 2-benzoyl-1,2,3,4,- tetrahydro-9H-pyrido-(3,4-b)-indole (III). Then compound (III) is reduced to give a 2-benzyl- 1,2,3,4-tetrahydro- 9H-pyrido-(3,4-b)-indole (IV). Thereafter, compound (IV) is chlorinated to a chloroindolenine derivative (V) which is treated with a dialkylmalonate salt such as thallium t-butyl methyl malonate to give a dialkyl 3-benzyl-1,2,3,4,5,6- hexahydroazepino-(4,5-b)-indole-5,5- dicarboxylate (VI) in which R5 is H, which is optionally alkylated. Compound (VI) is then partly decarboxylated into an alkyl 3-benzyl- 1,2,3,4,5,6-hexahydro-(4,5-b)-indole- 5-carboxylate which is hydrogenated to give an alkyl 1,2,3,4,5,6- hexahydroazepino-(4,5-b)-indole-5- carboxylate (VIII). In an alternative embodiment, compound (VI) can be hydrogenated to the corresponding dialkyl 1,2,3,4,5,6-hexahydroazepino- (4,5-b)-indole-5,5-dicarboxylate which is then decarboxylated into compound (VIII). Compound (VIII) is condensed with a functionalised aldehyde, typically an epoxy aldehyde or a haloaldehyde such as 1-bromo-4- formyl-hexane, to give vincadifformine or similar pentacyclic derivatives. Various intermediates and functionalised aldehydes are claimed per se. The individual steps of the process are also claimed.
