The Ru-catalyzed alkene-alkynecoupling reaction has been demonstrated to be an enabling methodology for the synthesis of complex molecules. However, to date, it has been limited to monosubstituted olefins. Herein we report the first general utilization of disubstituted olefins in the Ru-catalyzed alkene-alkynecoupling reaction by employing carbamate directing groups. The products are stereodefined
