AN APPROACH TO VINDOLINE SKELETON UTILIZING SUBSTITUTED METHYLENETETRAHYDROFOLATE (5,10-CHR-THF) MODELS

Starting from substitued methylenetetrahydrofolate model (4-(2-N(1)-tosyl-N(3)-methyl-4,4-dimethylimidazolidyl)-3-ketobutanoate), an efficient synthesis of the pentacyclic system corresponding to vindoline is described.
