Abstract

Ce pocédé de semi-synthèse de la vincamine à partir de tabersonine, comprend les étapes suivantes : on hydrogène la tabersonine en solution par le nickel de Rayney anhydre en vincadifformine; on salifie cette dernière par un acide, on oxyde la vincadifformine salifiée par un mélange anhydre, solide à température ambiante, d'acide maléique et d'acide permaléique à 40-50% du peracide; on transpose le composé oxydé par chauffage entre 30 et 50 degré C pendant 2-4 en obtenant la vincamine; et enfin, on isole cette dernière pour précipitation par l'ammoniaque.
