Abstract

The dynamic kinetic resolution of C4-aryl azlactones with alcohols was investigated by employing Brønsted acid catalysis. The reaction provided an efficient complementary approach to access chiral aryl glycine derivatives with excellent yields (up to 99%) and enantioselectivities (up to 96% ee).
