An efficient and practical hypervalent iodine compound mediated metal-free intramolecular aziridination reaction of allylic carbamates was developed. Analytically pure aziridines were obtained in high yields by simple filtration of the reaction mixture. In situ ring opening of the aziridines provides an easy access to useful vicinal amino alcohol derivatives and diamine compounds. Up to 16% ee was
开发了一种高效,实用的高价碘化合物介导的烯丙基氨基甲酸酯的无金属分子内叠氮反应。通过简单过滤反应混合物,可以高产率获得分析纯的氮丙啶。氮丙啶的原位开环使得容易获得有用的邻位氨基醇衍生物和二胺化合物。当使用手性高价碘化合物时,获得高达16%的ee。 叠氮化-高价碘-氨基甲酸烯丙酯-开环-邻二胺
