Abstract

2,4,5-Trisubstituted oxazoles were synthesized in good yields starting from α-methylene ketones by nitrosation, condensation with aldehydes and reduction with zinc in acetic acid at 40 °C. (5-Methyl-2-phenyloxazol-4-yl)ethanol was prepared by reduction of ethyl (5-methyl-2-phenyloxazol-4-yl)acetate with LiAlH4.
