Rs. Varma et D. Kumar, Manganese triacetate oxidation of phenolic Schiff's bases: Synthesis of 2-arylbenzoxazoles, J HETERO CH, 35(6), 1998, pp. 1539-1540
A concise synthesis of 2-arylbenzoxazoles, 5a-f, is described that occurs v
ia the oxidative cyclization of Schiffs bases, 1a-f, using relatively benig
n reagent, manganese triacetate.
