Several oxazoles and thiazoles were synthesized easily by the reaction of N-(methylthioalkylidene)glycine ethyl ester with diethyl oxalate, acid halides, and thionesters in the presence of base.

Transformation of alkyl N-(vinyloxy)benzimidates to alkyloxazoles proceeds through the intermediates: a charge-separated 1,2-oxazetidine derivative and then 1-hydroxy-2-imino>maleic acid diester, while their photochemical transformation takes place via a concerted sigmatropic shift.As the extension of this reaction, the preparation of the precursor proposed for virginiamycin M2 synthesis and the reaction of N-analogs of alkyl N-(vinyloxy)benzimidates are described.
