PEG-SO3H was found to be an effective heterogeneous catalyst for the one pot synthesis of various benzoxazole derivatives from condensation reaction between o-aminophenol with various aromatic aldehydes in ethanol to afford excellent yields. Synthesis was attempted at room temperature using ethanol as the solvent. Heterogeneity of the catalyst allowed its recycling for five times with almost retention in catalytic activity. Reaction carried out at room temperature shows special advantageous… CONTINUE READING
