摘要

Reactions of readily available N-(alkyl-, aryl-, and heteroarylsulfonyl) benzotriazoles 3a-h with diverse nitriles, reactive heteroaromatics, alkylheteroaromatics, sulfones, and esters produced α-cyanoalkyl sulfones 5a-i, sulfonylheteroaromatics 7a-e, α-(sulfonylalkyl) heterocycles 9a-f, α-sulfonylalkyl sulfones 11a-g, and esters of α-sulfonyl acids 14a-c, respectively, in synthetically useful to excellent yields. The results represent the first ...
