Ring opening reactions of N‐sulfonyl aziridines by primary and secondary amines in silica gel (SG)‐water system were achieved, which provided a mild, practical and environmentally benign method to synthesize mono‐ and bis‐sulfonyl substituted amines. When primary and secondary amines were used in excess, they reacted with N‐sulfonyl aziridines smoothly at room temperature, mainly affording 1:1 ring
在硅胶(SG)-水系统中,伯胺和仲胺会引起N磺酰基氮丙啶的开环反应,这为合成单磺酰基和双磺酰基取代的胺提供了一种温和,实用和环境友好的方法。当伯胺和仲胺过量使用时,它们与N-磺酰基氮丙啶在室温下平稳反应,主要提供1:1开环产物。伯胺与2当量的反应 的氮丙啶产生了2:1的开环产物。某些1:1的产物可以与CS 2环化,从而在水中也合成N-磺酰基环硫脲。
