Abstract

A process for the preparation of oxidation derivatives of (-) vincadiformin and (-) tabersonin, these compounds being defined by the formula: ** (see formula) ** And m and n each represent a hydrogen or a double bond, the process of which is characterized in that tabersonin, preferably obtained from voacanga grains, is treated by catalytic hydrogenation to give almost quantitatively (-) vincadiformin, (-) vincadiformin it is subjected to the action of oxidizing reagents to give a hydroxyindolenine (formula iv) and then a transposition of the hydroxyindolenine is carried out.
