Lewis-Base-Catalyzed Enantioselective Formal [4 + 2] Annulations of Morita–Baylis–Hillman Carbonates: Access to Tetrahydroquinolines Derivatives
Yanlin He, Wei Cai, You Huang
Abstract
The Lewis-base-catalyzed enantioselective formal [4 + 2] annulation reaction of o -acylamino-aryl MBH carbonates and electron-deficient olefins was developed. Tetrahydroquinolines with three sequential stereogenic centers containing a quaternary stereocenter were obtained in high yields with good enantioselectivity.
