Described herein is a novel concept for SN2 reactions at tertiary carbon centers in epoxides without activation of the leaving group. Quantum chemical calculations show why SN2 reactions at tertiary carbon centers are proceeding in these systems. The reaction allows flexible synthesis of 1,3‐diol building blocks for natural product synthesis with excellent control of the relative and absolute configurations
本文描述了在环氧化物中叔碳中心处的S N 2反应而不活化离去基团的新颖概念。量子化学计算表明为什么在这些系统中三级碳中心的S N 2反应正在进行。该反应可以灵活地合成1,3-二醇结构单元,用于天然产物的合成,并具有相对和绝对构型的出色控制。
