Asymmetric Synthesis of alpha-Alkylidene-beta-Lactams through Copper Catalysis with a Prolinol-Phosphine Chiral Ligand
A copper/prolinol-phosphine chiral catalyst enabled the one-step synthesis of chiral alpha-allcylidene-beta-lactams. Optimization of the chiral ligand for steric and electronic properties realized the highly enantioselective coupling of nitrones and propargyl alcohol derived alkynes. The resulting chiral alpha-allcylidene-beta-lactams served as a platform for various beta-lactams via well-established transformations of alpha,beta-unsaturated carbonyl compounds.
