- TfOH-Catalyzed Reaction of Bispropargyl Alcohols with 1,3-Dicarbonyl Compounds
-
A transition-metal-free efficient method for the preparation of 1,2,3-trisubstituted benzenes from bispropargyl alcohols and 1,3-dicarbonyl compounds has been developed. The reaction of bispropargyl alcohol with 1,3-dicarbonyl compound proceeds through [3,3]-rearrangement, 6π-electrocyclization, and unexpected Csp3-Csp2 regioselective σ-bond cleavage processes.
