Abstract

General method for preparation of oxazoles of formula (I): by heating a mixture of a nitrile of formula R'CN with a compound of formula: R2CO-CH(X)-R3 at 50-200 degrees C in an acid medium. In (I), R1, R2, R3 = H, aliphatic, cyclic, aromatic or heterocyclic group; X = halogen, OH, acyloxy. (I) are intermediates for dyestuffs, pharmaceuticals, plant-treatment agents, plastics and certain pyrimidines Also useful as solvents, stabilisers and pH control agents.
