stilbene-sydnone derivatives were synthesized by the following sequence of reactions: starting from methyl anthranilate via glycineand nitrosoglycine derivatives the corresponding 3-(o-carbomethoxyphenyl)-4-H/Me/Ph-sydnones were prepared and transformed to 3-(o-formylphenyl)-4-H/Me/Ph-sydnones, starting materials for Wittig reaction with various phosphonium salts to stilbenylsydnone derivatives. Final products
