Asymmetric Synthesis of Substituted Prolines from δ-Amino β-Ketoesters. Methyl (2S,5R)-(+)-5-Phenylpyrrolidine-2-carboxylate
摘要:
Metal carbenoid chemistry is used to convert delta-amino delta-ketoesters into 5-substituted 3-oxo prolines, which expands the utility of this class of polyfunctionalized chiral building blocks.

A chiral disulfonimide-catalyzed asymmetric synthesis of -amino--keto esters via a vinylogous Mukaiyama-Mannich reaction of the Chan diene with N-Boc imines has been developed. The desired products were obtained in good to excellent yields and enantioselectivities.
