A novel approach to chiral anti-α,β-diamino acid derivatives through tandem orthogonal organocatalysis has been developed. Chiral phosphoric acid catalysts control the chemo-, regio-, and stereoselective addition of hydroxylamines to alkylideneoxazolones, while a phosphine catalyst promotes the isomerization of Z- alkylideneoxazolones to the more reactive E- alkylideneoxazolones.

The orange fluorescing spot formed during the detection of halogenated hippuric acids with 4-N,N-Dimethylaminobenzaldehyde on TLC-plates consists of a E/Z-mixture of the corresponding benzyliden derivatives. Intermediates are the azlactones.
