Abstract

AbstractAn asymmetric bio‐ and organocatalytic cascade one‐pot reaction for the α‐arylation of aldehydes is presented. 1,4‐Dihydroxybenzene and its derivatives are oxidized to quinones by laccase and aerial oxygen. This catalytic process has been efficiently coupled to asymmetric enamine organocatalysis, affording 3‐substituted 2,3‐dihydrobenzofuran‐2,5‐diols in moderate to good yield and moderate to excellent enantioselectivity.magnified image
