A gold(I)-catalyzed decarboxylative amination of allylic N-tosylcarbamates via base-induced aza-Claisen rearrangement has been developed. A variety of substituted N-tosyl allylic amines were obtained in good yield, excellent regioselectivity, and high to excellent stereoselectivity. This transformation could be performed either in H2O or in one pot directly from allylic alcohols and therefore represents
已经开发了通过碱诱导的氮杂-克莱森重排的金(I)催化的烯丙基N-甲苯磺酰基氨基甲酸酯的脱羧胺化。以良好的产率,优异的区域选择性以及高至优异的立体选择性获得了各种取代的N-甲苯磺酰基烯丙基胺。该转化既可以在H 2 O中进行,也可以在一个罐中直接从烯丙基醇中进行,因此代表了合成N-甲苯磺酰基烯丙基胺的有效且环境友好的方案。
