The results showed that corresponding cis-and trans-β-sultams were generated in the reaction of benzyl sulfonyl chloride with benzylidene benzylamine, but no product when reacting with benzylidene aniline, which indicated that this reaction only occurred to N-alkyl substituted imines. 结果表明苄磺酰氯与苄叉苄胺反应生成了相应的顺式和反式β-磺内酰胺,而与苄叉苯胺无任何反应发生。表明N-烷基取代的亚胺才能发生反应。
