Abstract

Abstract Depending on their structures, imines are able to undergo either olefination or vicinal difunctionalization with various α-(benzothiazol-2-ylsulfonyl) carbonyl compounds in the absence of external bases. The olefination reaction of aromatic imines with α- (benzothiazol-2-ylsulfonyl) carbonyl compounds proceeds smoothly in tetrahydrofuran at 70 C to give structurally diverse α, β-unsaturated esters, amides, and ketones in good to ...
