摘要

2-(Methylsulfonyl)-2-(p-tolylsulfonyl) oxiranes 1 are easily prepared by the condensation of methylthiomethyl p-tolyl sulfone (MT-sulfone) with aldehydes and the subsequent oxidation with MCPBA. They smoothly reacted with 2 molar amounts of primary or secondary amines to give α-amino carboxamides in high yield. This reaction can be suitably extended to the reaction with one molar amount of 1, n-diaminoalkanes (n= 2, 3, or 4) to form the ...
