What is Indium-mediated One-pot Synthesis of Benzoxazoles or Oxazoles from 2-Nitrophenols or 1-Aryl-2-nitroethanones about?

One-pot reduction-triggered heterocyclizations from 2-nitrophenols to benzoxazoles and from 1-aryl-2nitroethanones to oxazoles were investigated. In the presence of indium/AcOH in benzene at reflux, 2nitrophenols and R-C(OMe) 3 (R1⁄4H, Me, Ph) produced excellent yields of corresponding benzoxazoles within an hour. Similarly, 1-aryl-2-nitroethanones and Ph-C(OMe) 3 in the presence of indium/AcOH in acetonitrile transformed into the corresponding oxazoles with good yields.
