实现了(+)-曲霉素B的高效全合成,其特点是通过C-糖基化反应构建2,6-反式取代的吡喃核心,高效的四步序列无需纯化即可产生关键中间体13,以及在高度复杂的底物上进行的有利的E-选择性Julia-Kocienski烯化反应。该合成证实了Uenishi对曲霉内酯B的结构进行了修正。
An efficient total synthesis of (+)-aspergillide B has been achieved, which features the C-glycosylation reaction for constructing the 2,6-trans-substituted pyran core, a highly effective four-step sequence without purification to produce the key intermediate 13 and an advantegous E-selective Julia-Kocienski olefination on a highly elaborate substrate. The synthesis confirmed the revised structure of aspergillide B by Uenishi.
