Mechanism and Origins of Enantioselectivity of Rhodium-Catalyzed [4+3] Annulation of Benzosilacyclobutenes with 7-Oxabenzonorbornadienes.
Rhodium-catalyzed asymmetric [4+3] annulation of benzosilacyclobutenes with 7-oxabenzonorbornadienes provides an efficient route to enantioenriched seven-membered sila-heterocycles. In this study, density functional theory calculations were performed to elucidate the reaction mechanism and the origins of the enantiosel...
