urea/thiourea in acidic medium afforded imidazolo oxazine derivative 3 and Imidazolothiazine 4. Coupling of 2a with benzene diazonium salt gave the phenyldiazenyl imidazolidine 5. While the reaction of 2a, thiourea, and benzaldehyde in sodium ethoxide afforded imidazolothiazine 6. Oxidative cyclization of thiourea derivative 7 resulted a mixture of benzithiazole derivative 7a and oxathiazole derivative 7b. Cyclocondensation
