An ultrafast synthesis of spiroketals by synergistic gold(I) and Sc(III) catalysis has been reported. Diverse 5,6-benzannulated spiroketals were rapidly constructed by the diastereoselective [4 + 2] cycloaddition between gold-generated enol ether and Sc(III)-catalyzed o-quinone methide intermediates. Ultrafast reaction rate,...

Bench-Stable 5-Stannyl Triazoles by a Copper(I)-Catalyzed Interrupted Click Reaction: Bridge to Trifluoromethyltriazoles and Trifluoromethylthiotriazoles.

Organic letters

Metalated triazoles are the key reactive intermediate of the current click reaction (CuAAC). Bench-stable 5-stannyl triazoles are obtained by a copper-catalyzed interrupted click reaction of easily available terminal alkynes. Subsequent palladium-catalyzed cross-coupling reactions, electrophilic trifluoromethylthiolation and trifluoromethylation, generate diverse...
