Abstract: A mild stereo‐ and regioselective Cu‐catalyzed hydroboration method for the synthesis of (Z)‐seleno‐alkenyl boronates and (Z)‐thio‐alkenylboronates from internal alkynes in the presence of commercially available B2pin2 is presented. This highly selective transformation relies on the… read more here.

Abstract: Construction of vinylsilane building blocks is important for advancing the synthesis of complex small molecules and natural products. Herein, we report a highly regio- and stereoselective copper-catalyzed hydrosilylation of unsymmetrical internal aryl alkynes. The reaction… read more here.

DOI: 10.1021/jacs.2c04043
Abstract: Direct asymmetric functionalization of the pyridyl C-H bond represents a longstanding challenge in organic chemistry. We herein describe the first enantioselective para-C-H activation of pyridines through the use of a Ni-Al bimetallic catalyst system and… read more here.
