A stereoselective synthesis of the C13-C23 segment of iriomoteolide-1a was achieved using, as key steps, a highly stereocontrolled crotylation to build the stereocenters at C18 and C19 and a Julia-Kocienski olefination to establish the C15-C16 E-olefin moiety.
通过采用高度立体控制的克罗提化反应建立C18和C19的立体中心,以及朱莉亚-科琴斯基烯化反应形成C15-C16 E-烯烃部分,成功实现了Iriomoteolide-1a的C13-C23片段的立体选择性合成。
