Cu(I)-Catalyzed Enantioselective and Stereospecific Borylative Annulation of Cyclic 1,3-Dione-Tethered 1,3-Enynes
A copper(I)-catalyzed, highly enantioselective, and diastereoselective borylative cyclization of prochiral cyclic 1,3-dione-tethered 1,3-enynes is reported. This stereospecific transformation exhibits a broad substrate scope, enabling access to bicyclic organoboron products containing…
