Acylation of ethyl acetoacetate with mesogenic para-substituted benzoyl chlorides, followed by cleavage of ethyl aroylacetoacetates thus obtained under basic conditions, gave the corresponding ethyl 3-aryl-3-oxopropanoates which were brought into condensations with hydroxylamine and hydrazine to obtain mesogenic 3-arylisoxazolones and 3-arylpyrazolones, respectively.
