Abstract
The condensation of 2-aminobenzothiazoles with α-bromo ketones products the fused imidazothiazole (2) whereas the analogous reaction with 2-aminobenzoxazoles gives the unexpected carbamate (10) or the fused imidazooxazole (13), depending on the nature of the starting materials. Isotope labelling studies as well as a proposed mechanism will be discussed.
