several elegant syntheses of (−)‐lasonolide A having been reported, a practical synthesis of this potent anticancer polyketide remains elusive. Based on the application of borane as a traceless protecting group and the development of an unprecedented bissulfone reagent for Julia olefination, (−)‐lasonolide A was assembled in an enantioconvergent manner through the application of stereoselective hydroboration
有效获得具有药用价值的天然产品是药物开发的重要基础。海洋天然产物的有限供应妨碍了广泛的生物学评估。尽管已经报道了(-)-Lasonolide A的几种优美的合成方法,但这种有效的抗癌聚酮化合物的实用合成方法仍然难以捉摸。基于硼烷作为无痕保护基的应用以及空前的双砜试剂用于Julia烯化的发展,通过立体选择性加氢硼化,烯丙基化和氧化,以对映体收敛的方式组装了(-)-lasonolide A. 这种简洁的途径可以为访问派生词和类似物提供现实的解决方案。
