Ru(II)-Catalyzed Chemo- and Regioselective Cyclotrimerization of Three Unsymmetrical Alkynes through Boron Temporary Tether. One-Pot Four-Component Coupling via Cyclotrimerization/Suzuki−Miyaura Coupling

The Ru(II)-catalyzed [2+2+2] cyclotrimerization of alkynylboronates, propargyl alcohol, and terminal alkynes proceeded chemo- and regioselectively to give rise to arylboronates, which were subjected to Suzuki−Miyaura cross-coupling with aryliodides to afford highly substituted biaryls in 53−76% yiel...
