Selenium mediated cyclization reaction of isonitriles with o-aminophenols leading to 2-aminobenzoxazoles has been reported. The present method, which simply utilizes element selenium as promoter and tBuONa as base, provides a green and efficient approach to synthesize various 2-aminobenzoxazoles under mild conditions. This reaction has the advantages of simple operation and metal-free condition. 2-Aminobenzothiazole and 2-aminobenzimidazole could also be synthesized through this methodology.

Key words: metal-free, selenium, isonitriles, o-aminophenols, 2-aminobenzoxazoles
