A decarboxylative cross-coupling reaction of α-aminoacids with nitrones via visible-light-induced photoredox catalysis has been established for easy access to β-amino hydroxylamines and vicinal diamines with structural diversity, which is featured with simple operation, mild conditions, readily available α-aminoacids, and a broad scope of nitrone substrates. The application of this protocol can furnish
The scope and potential of the reaction have been investigated and developed. The reaction can also be catalyzed by secondaryamines. The use of chiral cyclic amines, such as L-proline leads to optically active beta-hydroxynitrones in moderate yield and with moderate to high enantiomeric excess. The reaction mechanism was studied by kinetic measurements, intermediate and product analysis, and determination
