A novel enantioselective synthesis of 6H-dibenzopyran derivatives by combined palladium/norbornene and cinchona alkaloid catalysis

Org Biomol Chem. 2015 Feb 28;13(8):2260-3. doi: 10.1039/c4ob02551b.

Abstract

Organometallic and organo-catalysts are cooperatively at work in the enantioselective synthesis of dibenzopyran derivatives; palladium/norbornene and a cinchona alkaloid base guarantee good yields and satisfactory enantioselectivities in a one-pot reaction.
