Synthesis of 4-sulfonyl-1,7-diesters via K₂CO₃-mediated alkylative debenzoylation of α-sulfonyl o-hydroxyacetophenones with acrylates

Abstract

The synthesis of 4-sulfonyl-1,7-diesters was well-developed, under the open-vessel condition, by K2CO3-mediated double alkylation of α-sulfonyl o-hydroxyacetophenones with acrylates, and tandem debenzoylation of the resulting α,α-disubstituted o-hydroxyacetophenones. A plausible mechanism...
