Abstract: An effective strategy for the ring-opening/elaboration of cyclopropanes by phosphine catalyst is documented, providing the 2,4-pentadiene sulfonamides and isoindolines in moderate to good yields. The key to the success of this reaction is phosphine-catalyzed introduction… read more here.

Abstract: This review concentrates on recent developments from our laboratory concerning the Rh-catalyzed carbonylative C-C bond activation of cyclopropanes. Specifically, we have found that N-based directing groups are effective at controlling the regioselectivity of C-C bond… read more here.
