Abstract
Procedure for the preparation of cunarine compounds of formula I **(See formula)** in which X stands for oxygen, sulfur or the sulfonyl group, Y means a mononuclear carbocyclic or heterocyclic aryl groups, which is in conjugation with the coumarin ring, and the coumarin ring, as well as the benzene nucleus A may still be substituted by halogen, lower alkyl and/or alkoxy groups, characterized in that an oxime of formula III, it is reacted in a weakly acidic medium with a coumarinylhydrazine of the formula IV, **(See formula)** which may still be correspondingly substituted on the coumarinyl ring to form the corresponding oxyhydrazone and this is transformed with the aid of a condensing agent into a compound of formula I.
