approach to the synthesis of medium-ring lactones is reported based on sequential Evans-Tishchenko and ring-closing metathesis (RCM) reactions. High diastereoselectivity (>95:5) is demonstrated in the Evans-Tishchenko reaction of unsaturated aldehydes with unsaturated beta-hydroxy ketones, and conditions for the RCM cyclization of the resultant dienes have been optimized to give high yields of medium
据报道,基于顺序的Evans-Tishchenko和闭环复分解(RCM)反应,一种合成中环内酯的新方法。在不饱和醛与不饱和β-羟基酮的Evans-Tishchenko反应中证明了高非对映选择性(> 95:5),并且优化了所得二烯的RCM环化条件以提供高收率的中环内酯。该序列的合成效用通过生成八官能肌动蛋白A的完全功能化的核心来证明。
