1	TfOH-catalyzed reaction of bispropargyl alcohols with 1,3-dicarbonyl compounds Teng, Q., Mo, S., Pan, J., Wu, Na, Wang, H., Pan, Y. 03 June 2020 (has links) No / 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.
