strategy for the assembly of the entire carbon backbone of a stereoisomer of the antitumor marine natural product hemicalide has been investigated. The devised convergent approach relies on Horner–Wadsworth–Emmons and Julia–Kocienski olefination reactions for the construction of the C6=C7 and C34=C35 double bonds, respectively, an aldol reaction to create the C27−C28 bond, and a Suzuki–Miyaura cross‐coupling

天然产物hemicalide的立体异构体的整个碳骨架的策略。拟定的收敛方法分别依赖于霍纳-沃兹沃思-埃蒙斯和朱莉娅-科辛斯基的烯化反应分别构建C6 = C7和C34 = C35双键,形成C27-C28键的羟醛反应以及Suzuki-Miyaura交叉耦合作为形成C15-C16键的最终选择。
