A new asymmetric total synthesis of (-)-malyngolide is described. This synthesis is based on the originally developed catalytic asymmetric IMCP reaction; that is, α-diazo-β-keto sulfone (13) was successfully converted to cyclopropane (12) in 92 % yield with excellent enantioselectivity (97% ee), and cyclopropane (12) was successfully converted to (-)-malyngolide.
描述了一种新的 (-)-malyngolide 的不对称全合成方法。该合成基于最初开发的催化不对称 IMCP 反应;也就是说,α-重氮-β-酮砜 (13) 成功地转化为环丙烷 (12),收率为 92%,对映选择性 (97% ee) 优异,环丙烷 (12) 成功转化为 (-)-malyngolide。
