  • GEM-DISUBSTITUTED PYRROLIDINES, PIPERAZINES, AND DIAZEPANES, AND COMPOSITIONS AND METHODS OF MAKING THE SAME
    Publication number: 20220213081
    Abstract: Described here are transition metal-catalyzed enantioselective arylation and vinylation reactions of ?-substituted lactams, such as ?-lactams. The use of various electrophiles and ligands are described, and result in the construction of ?-quaternary centers in good yields (up to 91% yield) and high enantioselectivities (up to 97% ee).
    Type: Application
    Filed: December 31, 2021
    Publication date: July 7, 2022
    Inventors: Brian M. Stoltz, Alexander W. Sun, Stephan N. Hess, Carina I. Jette, Irina Geibel, Shoshana Bachman, Masaki Hayashi, Hideki Shimizu, Jeremy B. Morgan, Shunya Sakurai, Zachary P. Sercel
