Phosphine/Palladium Cooperative Catalysis: Enantioselective [5+4] Annulations of ortho-Quinone Methides and Vinylethylene Carbonates

Org. Chem. Front., 2020, Accepted Manuscript
DOI: 10.1039/D0QO00128G, Research Article
Chao Xia, Dong-Chao Wang, Gui-Rong Qu, Hai-Ming Guo
Highly enantioselective [5+4] annulations of ortho-quinone methides with vinylethylene carbonates were enabled by phosphine/palladium asymmetric cooperative catalysis for the first time. Efficient synthesis of various nine-membered benzo-heterocycles was achieved in...
