(+)−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
(+)-长春胺(1)和(+)-长春西汀(2)被氯磺酰化并且所得磺酰氯异构体(3-6)被转化为磺酰胺(7-10)。通过选择性水解和酯交换来修饰磺酰胺的酯基。Apovincaminol 衍生物 (14-16) 也通过还原制备。除了未取代化合物 (1,2) 的已知脑血管作用外,磺胺类药物还显示出显着的外周血管扩张作用。
