Article abstract of DOI:10.1002/ardp.19923250706

3-(3 or 4-Acetylphenyl)-sydnones 7, 8 have been synthesized by formation of the glycines 3, 4, followed by nitrosation to 5, 6 and cyclization with acetic anhydride to sydnones. Sydnone derivatives carrying chalcone moieties 15, 16 were prepared by format
