The first total synthesis of chondrochloren A is accomplished using a 1,2‐metallate rearrangement addition as an alternative for the Nozaki‐Hiyama‐Kishi reaction. This transformation also avoids the inherent challenges of this polyketide segment and provides a new, unprecedented strategy to assemble polyketidal frameworks. The formation of the Z‐enamide is accomplished using a Z‐selective cross coupling
1,2-金属盐重排加成反应作为Nozaki-Hiyama-Kishi反应的替代方法,完成了软骨素A的第一个全合成。这种转变还避免了该聚酮化合物链段的固有挑战,并提供了组装聚酮化合物骨架的新的,前所未有的策略。Z-烯酰胺的形成是通过相应酰胺与Z-乙烯基溴的Z-选择性交叉偶联来完成的。
