The conventional Wenker synthesis of aziridines from vicinal amino alcohols has been modified by employing mild reaction conditions. Amino alcohols were converted into their hydrogen sulfates with chlorosulfonic acid. The sulfates were cyclized with sodium hydroxide, and even with non-nucleophilic sodium carbonate. The current, improved method extends the scope of the typical Wenker synthesis and is
通过使用温和的反应条件,已改变了由邻氨基氨基醇合成传统的Wenker氮丙啶的方法。用氯磺酸将氨基醇转化为硫酸氢盐。硫酸盐用氢氧化钠甚至非亲核碳酸钠环化。当前改进的方法扩展了典型的Wenker合成的范围,并且适用于热硫酸中的不稳定氨基醇,以及适用于在强碱存在下有利于消除和氢氧化物置换的不稳定硫酸盐。 氨基醇-氮丙啶-硫酸氢盐-Wenker合成
