Abstract: A study on a rhodium(II)-catalyzed reaction of N-sulfonyl-1,2,3-triazoles with 2-alkenols is reported. The reaction is initiated by insertion of an α-imino carbene into the O–H linkage of alcohol, forming a 2-alkenoxy enamide intermediate. A thermal… read more here.

Abstract: Dual Rh(II)/Pd(0) relay catalysis of N-sulfonyl triazoles and 2-hydroxymethylallyl carbonates has been developed, which affords N-sulfonyl pyrrolidines in moderate to good yields with high diastereoselectivities. The reaction proceeds via a relay mechanism involving O-H insertion… read more here.

Abstract: A novel relay Rh (II)/cobaloxime (III) dual catalysis strategy has been developed for the stereoselective synthesis of indolyl spiroindanones from readily accessible N-sulfonyl-1,2,3-triazoles. This binary-catalyst system enables an aza-vinyl carbene initiated Pictet-Spengler-type cyclization and sequential… read more here.
