preparation of a novel simplified Laulimalide analog via a highly convergent and efficient route and its biological evaluation are presented. The outlined route enables the synthesis of C5–C9 modified analog 2 and uses Julia–Kocienski olefination for fragment assembly and a regioselective Yamaguchi macrolactonization for ring closure. This strategy should be suitable for the generation of various new
介绍了通过高度收敛和高效的途径制备新型简化的劳力马胺类似物及其生物学评价。概述的路线能够合成C 5 -C 9修饰的类似物2,并使用Julia-Kocienski烯烃进行片段组装,并使用区域选择性Yamaguchi大内酯化进行环封闭。该策略应适合于生成各种新的C 5 -C 9 des -dihydropyran laulimalide衍生物,以用于进一步的SAR研究。
