A one-pot synthesis of 2-methylthio-1,3-oxazoles by a cyclocondensation reaction between dimethyl N-(ethoxycarbonylmethyl)iminodithiocarbonate and S-phenyl alkanethioates and thiobenzoates is described. The new procedure offers several advantages: easy access of the reagents, high selectivity, and facile introduction of different substitutions in the heterocyclic ring.
一种一步合成2-甲硫基-1,3-噁唑的方法是通过二甲基N-(乙氧羰甲基)亚胺二硫代碳酸酯与S-苯基烷硫醇酯及硫苯甲酸酯之间的环缩合反应来实现的。该新方法具有多个优点:试剂易得、高选择性以及异环中不同取代基的方便引入。
