Iridium-Catalyzed Asymmetric Allylic Substitution with Sequential Boron Incorporation

An iridium-catalyzed asymmetric allylic substitution with sequential boron incorporation is reported. The reaction accommodates a wide range of substrates, affording chiral N,O-bidentate difluoroboron complexes in excellent yields with high enantioselectivities. Furthermore, decigram-scale reaction, synthetic transformations, as well as photophysical property investigations of the N,O-bidentate difluoroboron complexes are explored.
