摘要

Sulfone compounds have drawn increasing attention in organic synthesis. Among their derivatives, β-keto sulfones display a broad range of synthetic versatilities 1 and 2 and some exhibit fungicidal activity. 3 Considering the importance of β-keto sulfones, the development of synthetic methodology for β-keto sulfones is of great interest. The existing approach includes: (i) acylation of α-sulfonyl carbanions; 4 (ii) alkylation of metallic arene sulfinates; ...
