Abstract
Abstract 1-Aryl-2-(4-nitrophenylsulfonyl)ethanones (1) reacted with one equiv. of α,β-unsaturated esters at 60°C to afford the tandem addition-rearrangement products (3), while at 75°C 1a reacted with two equiv. of methyl acrylate and gave an unexpected addition-rearrangement-addition-annulation product which is dimethyl 4-hydroxyl-1-(4-nitrophenyl)-4-phenyl-1,3-cyclohexyldicarboxylate (4). A mechanism is suggested.
