thiazole and thiazine derivatives, respectively. However, isoindole derivatives 24 and 26 were formed on heating of 1 with either tetrabromophthalic anhydride and=or o-phthalaldehyde, respectively. The products were fully characterized according to their spectral data. The mechanisms of formation of the products have been rationalized.
