Abstract

(+)-Vincamine (1) and (+)-vinpocetine (2) were chlorosulfonylated and the resulting sulfonyl chloride isomers (3-6) were transformed into sulfonamides (7-10). The ester group of sulfonamides was modified by selective hydrolysis and transesterification. Apovincaminol derivatives (14-16) were also prepared by reduction. In addition to the known cerebrovascular effects of the unsubstituted compounds (1,2) sulfonamides also show a significant peripheral vasodilator effect.

摘要

(+)-长春胺(1)和(+)-长春西汀(2)进行氯磺酰化反应,所得的磺酰氯异构体(3 - 6)转化为磺酰胺(7 - 10)。通过选择性水解和酯交换反应对磺酰胺的酯基进行修饰。还通过还原反应制备了阿朴长春胺醇衍生物(14 - 16)。除了未取代化合物(1,2)已知的脑血管作用外,磺酰胺还显示出显著的外周血管舒张作用。
