give analogous benzoxazoles, naphthoxazoles, benzothiazoles and benzimidazoles. A mechanistic proposal has been drawn based upon the control experiments. It was demonstrated that under the influence of aerobic conditions the catalytic amounts of tBuOOH can be generated by auto-oxidation of tert-butoxide base which plays a decisive role towards successful completion of the developed approach. The described

A facile route to benzoxazoles has been developed using microwave-assisted dielectric heating. The ease of synthesis and workup allowed the parallelsynthesis of a 48-membered library of benzoxazoles quickly and efficiently.
