Enantioselective 4-Hydroxylation of Phenols under Chiral Organoiodine(I/III) Catalysis

Abstract

A procedure for the intermolecular enantioselective dearomatization of phenols under chiral (I/III) catalysis is reported. This protocol employs mCPBA as the terminal oxidant together with a defined C2-symmetric aryl iodide as the effective organocatalyst. This enantioselective reaction proceeds with complete selectivity under mild conditions and enables the hydroxylative dearomatization of a number of phenols into the corresponding para-quinol products with up to 50
