Abstract
o-Aminophenols react with alcohols in the presense of a catalytic amount of ruthenium catalyst at 180℃ to give 2-substituted benzoxazole in good yield. The yields of 2-substituted benzoxazoles were affected by the yield of N-alkylation compound from o-aminophenol and alcohol as starting materials. During the reaction, a stoichiometric amount of hydrogen was spontaneously evolved into the gas phase.
