spectrum of biological activity. Methods have been developed [12-16] for the preparation of substituted 2-buten-4-olides with a variety of function&l substituents. In order to obtain new compounds containing the 2-buten-4-olide ring and to examine their antiviral activity, we have carried out some chemical reactions of 2-acyl derivatives of 2-buten-4-olides (I-III), in whichthe lactone ring is conserved, as
