[reaction: see text] The challenging structural features and important biological activity of (+)-compactin (1) explain the substantial synthetic interest that it has generated. We report a novel enantioselective approach to the advanced intermediate 2a, which constitutes a formal synthesis of (+)-1. The sequence utilizes MacMillan's organocatalytic Mukaiyama-Michael reaction, which stereoselectively
[反应:见正文](+)-compactin(1)具有挑战性的结构特征和重要的生物学活性可解释其产生的大量合成兴趣。我们报告了一种先进的中间体2a的新型对映选择性方法,该方法构成了(+)-1的形式合成。该序列利用了麦克米伦的有机催化Mukaiyama-Michael反应,该反应将甲硅烷氧基呋喃6立体选择性地添加到α,β-不饱和醛7中。在该反应中产生的手性可指导2a中其他三个连续的立体中心的形成。
