A cascade reaction of cyclopropyl alcohols, DABSO (1,4-diazoniabicyclo[2.2.2]octane-1,4-disulfinate), and N-(sulfonyl)acrylamides has been developed. This tandem process went through a cyclopropanol ring opening Michael addition sequence. The γ-keto sulfinate generated from the between serves as nucleophilic reagent, N-(sulfonyl)acrylamide is used acceptor. By utilizing this strategy, multitudinous sulfone-bridged 1,7-dicarbonyl compounds that contain both β-sulfonyl amide unit sulfone skeleton were conveniently synthesized.
