A General Route to Silacyclohexanones via Regioselective Copper-Catalyzed Borylative Cyclization

Abstract A copper-catalyzed regioselective borylative cyclization of chloromethyl butenylsilanes with bis(pinacolato)diboron has been reported. The reaction proceeds via an endo-selective cyclization to deliver 4-silacyclohexyl boronates, which undergo a two-step oxidation sequen...
