摘　　要：氨甲酰基硅烷与N-磺酰亚胺在无催化剂苯作溶剂的条件下反应,直接合成了磺酰基保护的α-氨基酰胺衍生物,收率为71%~89%.该方法不仅可合成α-氨基叔酰胺,还可合成α-氨基仲酰胺.通过研究反应的影响因素发现,N-磺酰亚胺双键相连基团旳电子效应是影响反应的重要因素,它既影响反应完成的时间,又影响产物的产率.该反应具有条件温和、副产物少、产率高和后处理简单等优点,是有效合成α-氨基酰胺的新方法.α-（N-Sulfonyl）amino amide derivatives are directly synthesized in 71%~89% yields by the reaction of carbamoylsilanes with various N-sulfonylimines in benzene under catalyst-free conditions. The procedure can prepare both tertiary and secondary α-amino amides. A comparison of the results obtained from the N-sulfonylimines containing the variety of alkyl, aryl and heterocyclic ring indicated that the electronic effect was an important factor in the addition reaction, which influenced on the rate and yields of the reaction. The new method is simple and mild procedure, no catalysts conditions, less byproducts and good yields for the preparation of α-aminoamides
