We report herein an unprecedented atroposelective dynamic kinetic resolution of Bringmann’s lactones with C-nucleophiles. By the use of activated isocyanides as the reagent, a wide range of novel axially chiral oxazole-substituted biaryl phenols were accessed in high yields with high enantioselectivities. Key to the success of this process lies in the tandem atroposelective addition of isocyanides to the lactone substrate followed by a rapid cyclization, overcoming the challenge of stereochemical leakage induced by lactol formation.
