Mesoionic 1,3-oxazolium-5-olates (munchnones) react fairly rapidly with oxygen to give the autoxidation products when the C-4 substituent is aromatic. The autoxidation occurred in the munchnones generated from N-acyl tetrahydroisoquinoline-1-carboxylic ac

The title compounds (2a-g) were formed from N-acetyl-N-alkyl-α-amino acids (1a-g) on treatment with trifluoroacetic anhydride in the presence of pyridine. The structure of the product (2a) was determined by single crystal X-Ray analysis.
