Abstract
Procedeu pentru prepararea vincaminei si stereoizomerilor sai cu formula I: (vezi form. in desc.) caracterizat prin aceea ca se transforma vincaminolul si/sau stereoizomerii sai cu formula II:(vezi form. in desc.) prin deshisratare oxidativa sub act iunea anhidridei fosforice si a dimetilsulfoxidului la o temperatura cuprinsa între 0 si 150 degree C, de preferinta, în prezenta de piridina, în apovincaldehida si sau stereoizomerii sai cu formula III: (vezi form. in desc.) prin deshidratare oxidativa subactiunea anhidridei fosforice si a dimetilsulfoxidului la o temperatura cuprinsa între 0 si 150 degree C, de preferinta, în prezenta de piridina, în apovincaldehida si sau stereoizomerii sai cu formula III: (vezi form. in desc.) care apoi se transforma pri n tratare cu o cianura alcalina, de exemplu, cu cianura de sodiu si acid acetic în metanol în prezenta bioxidului de mangan, la temperatura ambianta, în aprovincamina si sau stereoizomerii sai formula IV:(vezi form. in desc.)
