Eine neue合成von vinblastinderivaten iv。:合成von 20'-deethyl.-20'-deoxyvinblastin und 20'-deethyl-20'-deoxyvincovalin uber 3,N b -seco-leavmin-derivate als zwischenstufen
摘要:
的耦合外消旋16-甲氧基羰基-15,20-二氢3,N b -开环-cleavamine衍生物34( - )经由chloroindolenine中间体41文多灵环化于可分离二聚体46I和46II与天然℃后高立体选择性和引线发生(14′),C(16′)-构型具有良好的产率。制备具有长春碱类似立体化学的四环内酰胺37,并将其转化为氯吲哚胺38。以良好的收率实现了38与N,N-二甲基-间-茴香胺的偶联。
