A series of N-protected 1-substituted homotaurines was synthesized efficiently from various olefins with O-ethyl S-2-phthalimidomethylxanthate as a sulfur-aminomethylation reagent via a radical addition and subsequent performic acid oxidation. The current method is a convenient and practical method for the synthesis of 1-substituted homotaurines with high yields and short synthetic route.
用O-乙基S -2-邻苯二甲酰亚胺基甲基黄原酸酯作为硫-氨基甲基化试剂,通过自由基加成和随后的甲酸氧化,由各种烯烃有效地合成了一系列的N-保护的1-取代的高牛磺酸。目前的方法是合成高产率和短合成路线的1-取代高牛磺酸的方便实用的方法。
