This communication details the first total synthesis of the 13-membered macrolide, (−)-Melearoride A, as well as unnatural (+)-Melearoride A. The synthesis features a concise 13 step synthesis (11 steps longest linear sequence) that offers flexible stereo-control and multiple opportunities for unnatural analog synthesis to delve into antifungal SAR. The route features a cuprate addition, an Evans asymmetric
本交流详细介绍了13元大环内酯类化合物(-)-美洛瑞A以及不自然的(+)-美洛瑞A的首次全合成。该合成具有简洁的13步合成法(最长11步线性序列),可提供灵活的立体控制以及非自然模拟合成深入研究抗真菌SAR的机会。这条路线的特点是添加了铜酸盐,埃文斯不对称烷基化和闭环易位(RCM),以关闭13元大环核心。
