摘要

The present invention relates to a compound of formula (I) wherein A represents a bidentate group of the formula —CH — X — CH— (wherein X represents methylene, sulfur or oxygen), X'C = CY or X'WC-CYZ (where X ', W , Y and Z independently represent hydrogen, hydroxy, acyloxy, alkoxy, alkylsilyloxy, cyano or halogen, or X 'and W or Y and Z together with the carbon to which they are attached form a carbonyl group), provided that A is not CH-CH; Ar is an optionally substituted phenyl or 5- or 6-membered heterocyclic ring system containing from 1 to 3 heteroatoms selected individually from nitrogen, oxygen and sulfur, and at least one unsaturation (double bond) between adjacent atoms in ring, and the specified heterocyclic ring optionally condensed with a benzene ring, where the substituents, if present, are selected from halogen atoms, cyano, alkyl, alkenyl, alkynyl, alkoxy, haloalkyl, halogenoalkenyl, alkylthio and alkylamine ogroup, each of which contains up to six carbon atoms; R is a hydrogen or a cyano or a group selected "represents oxygen or a group NR), provided that when R represents alkenyl, aralkenyl or alkynyl, this group does not contain an unsaturated carbon atom directly attached to the nitrogen ring of the formula (I); R 2 is hydrogen, cyano, hydroxy, alkyl, alkoxy, amino, nitro, isocyanato, acylamino, hydroxyalkyl, optionally substituted
