By a combination of cyclodehydration of N-acyl amino acids with N,N′-diisopropylcarbodiimide (DIC) and non-classical Wittig olefination of the resultant 5(4H)-oxazolones with Ph3PCHCN and Ph 3PCHCOOEt, 5-oxazoleacetonitriles and 5-oxazoleacetates were synthesized in one-pot in 41-85% and 57-70% yields, respectively.

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.
