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