Mixtures of stereoisomers of oxiranylhydroxytetrahydropyrimidines were obtained by cyclocondensation of a-arylacrylyloxiranes with acetamidines or benzamidines; the 2-aryl derivatives of the products give the corresponding dihydropyrimidines and pyrimidines under base-catalysis conditions~ In acetic
