Abstract

The Gould-Jacobs reaction of all position isomeric 2-aminonitrobenzothiazoles II with diethyl ethoxymethylenematonate has been studied. Thestructure of substitution (IV) and cyclization (VI) products and of the corresponding acids (VIII) was confirmed by elemental analysis, IR,UV, H-1 and C-13 NMR spectra. Analogous derivatives III, V and VII, derived from the unsubstituted 2-aminobenzothiazole I, were used as standards in interpretation of the spectra. The synthesized derivatives I- VIII were tested for antimicrobial activity.
