In this article, Huang and co-workers describe a Pd-catalyzed stereodivergent [4 + 2] annulation reaction of alkylidene pyrazolones with vinyl benzoxazinanones via ligand regulation. The reaction produces an array of [6.5]-spiropyrazolones with three contiguous stereocenters in high yields and stereoselectivities. The origin of this stereodivergent annulation process was revealed by DFT calculation.
In this issue of Chem Catalysis, Huang and co-workers report a Pd-cata-lyzed stereodivergent [4 + 2] annulation of alkylidene pyrazolones with vinyl benzoxazinanones via ligand regulation, synthesizing an array of [6.5]-spiropyrazolones bearing three contiguous stereocenters with high yields and stereoselectivities. The origin of this stereodivergent annulation process was revealed by DFT calculation.
