Abstract

Procédé pour la préparation d'éburnamonines de formules générales (2) ou (3) et de leurs dérivés en partant de vincamines ou d'acides vincaminiques de formule générale (4a) ou (4b) ou de leurs dérivés caractérisé en ce que l'on soumet les vincamines de formules 4a et 4b à un processus d'électrolyse en solution alcoolique ou hydroalcoolique.Process for the preparation of eburnamonins of general formulas (2) or (3) and their derivatives starting from vincamines or vincaminic acids of general formula (4a) or (4b) or their derivatives characterized in that the vincamines of formulas 4a and 4b are subjected to an electrolysis process in alcoholic or hydroalcoholic solution.
