Reacting vicinal epoxymesylates of general structure i with higher order and mixed higher order organocuprate reagents is shown to be very selective for attack at the least hindered epoxide center. The iterative application of this reaction - a sequence which consists of cuprate opening of epoxide i, reformation of an epoxide (I→ii), and subsequent cuprate opening of this intermediate epoxide (ii→iii)
已表明,一般结构i的邻位环氧甲磺酸酯与较高阶的有机铜酸酯试剂和混合的较高阶的有机铜酸酯试剂反应对于在最少受阻的环氧中心的进攻非常有选择性。该反应的迭代应用-由环氧化物i的铜酸盐开放,环氧化物的重整(I→ii)和随后的中间环氧化物(ii→iii)的铜酸盐开放组成的序列-提供了易于接近的无环碳构架最多三个连续的立体生成中心。
