Photoredox-Catalyzed Decarboxylative Cross-Coupling of -Amino Acids with Nitrones

A decarboxylative cross-coupling reaction of alpha-amino acids with nitrones via visible-light-induced photoredox catalysis has been established for easy access to beta-amino hydroxylamines and vicinal diamines with structural diversity, which is featured with simple operation, mild conditions, readily available alpha-amino acids, and a broad scope of nitrone substrates. The application of this protocol can furnish efficient synthetic strategies for some valuable vicinal diamine-containing molecules.
