Synthesis of vincaminic acid derivatives |
| abstract |
Abstract: A process is described for producing vincaminic acid derivatives of formula (A) in which R is methyl or ethyl and X is hydroxy or hydrogen and Y is hydrogen or X and Y together form a double bond, these derivatives being useful in treatment of cerebral insufficiencies. The process is carried out starting from an enamine of the formula (1) (1) |
