methyl carbamate, triethyl orthoformate, and readily available alkenes provides a highly practical preparation of protected aminocyclopropanes. The reaction proceeds with preferential cis addition to alkenes, and cleavage of the methyl carbamate gives the free aminocyclopropanes as their HI salts (see scheme).
简单如 1,2,3:氨基甲酸甲酯、原甲酸三乙酯和容易获得的烯烃的反应提供了一种高度实用的受保护氨基环丙烷制备方法。该反应通过优先顺式加成到烯烃进行,氨基甲酸甲酯的裂解得到游离氨基环丙烷作为它们的 HI 盐(参见方案)。
