Abstract

Diazotization of N-benzylidene anthranilic acids 1a–1n at pH 9 yielded N-[α-(phenylazo) benzylidene] anthranilic acids 2a–2n and at pH 3 yielded N-benzylidene-5-(phenylazo) anthranilic acids 3a–3n. When compounds 3a–3n were treated with thioglycolic/thiolactic acid in the presence of anhydrous ZnCl2, 2-(4-oxo-2-phenylthiazolidin-3-yl)-5-(phenylazo) benzoic acids 4a–4n were afforded. The newly synthesized compounds were screened ...
