Complementary selectivity can be achieved in ring opening reactions of 2-aziridinemethanols by using either the Gilman reagent or lower order cyanocuprate. In the former case, the usual attack of the Gilman reagent to the substrates 1 and 2 results in the formation of the expected ring opening products (3 and 4) and (7 and 8), respectively. In contrast, exposure of both 1 and 2 to the lower order cyanocuprate
可以通过使用吉尔曼试剂或低级氰尿酸酯在2-氮丙啶甲醇的开环反应中实现互补的选择性。在前一种情况下,吉尔曼试剂对底物1和2的通常攻击导致分别形成了预期的开环产物(3和4)和(7和8)。相反,将1和2都暴露于低级氰铜酸盐中却以前所未有的方式进行,大概是通过环氧化物D和G来生成意想不到的仲醇(11和12)作为主要产品。
