A fast and general synthesis of quinoxalines, performed in two stages or as a one-pot reaction, starting from ketones via their a-hydroxylimino ketone derivatives, and condensation of the latter with 1,2diaminobenzene under microwave irradiation, is described.
## Abstract An efficient and clean two step procedure for the synthesis of imidazo[2,1β__b__]oxazoles has been developed from 2βaminooxazoles using titanium(IV) chloride assisted cyclization, and a variety of imidazo[2,1β__b__]oxazoles have been synthesized in good yields. The structure of one of t
