Abstract
AbstractA copper‐catalyzed asymmetric oxidative cross‐coupling reaction of 2‐naphthols with aryl methyl ketones has been developed. This transformation provides an efficient route to various functionalized naphtho[2,1‐b]furan‐1(2H)‐ones in an enantiomerically enriched manner with molecular oxygen in air as the oxidant (52–89 % yields, up to 87 % ee). The reaction leads to the formation of a new quaternary carbon center within 3(2H)‐furanones.
