H2O–1,4-dioxane and without an additional catalyst, the rearrangements of various types of cyclopropyl carbinols were attempted. It was found that the reactions generally gave homoallylic alcohols in good to very high chemical yields. Rearrangements of bicyclic or tricyclic cyclopropyl carbinols readily gave the desired ring-expanded cyclic homoallylic alcohols which are difficult to synthesize by other
在回流9:1(v / v)H 2 O–1,4-二恶烷且没有其他催化剂的情况下,尝试对各种类型的环丙基甲醇进行重排。发现该反应通常以高至非常高的化学产率得到均烯丙基醇。双环或三环环丙基甲醇的重排容易得到所需的扩环环状均烯丙基醇,其难以通过其他方式合成。
