Abstract
A compound of formula (I): ##STR1## in which Ar is an optionally substituted aryl or heterocyclic ring system; W is O or NR.sup.1 where R.sup.1 is hydrogen or lower alkyl; PA1 A is .dbd.CH or >CH.sub.2 and G is .dbd.C--R.sup.2, >CR.sup.3 R.sup.4 or >C.dbd.R.sup.5 such that --G--A-- is --CR.sup.2 .dbd.CH--, where R.sup.2 is H or CR.sup.6 R.sup.7 XR.sup.8 ; or --G--A-- is CR.sup.3 R.sup.4 --CH.sub.2 where CR.sup.3 R.sup.4 is CH--CR.sup.6 R.sup.7 XR.sup.8, CH--OCR.sup.6 R.sup.7 XR.sup.8, C(R.sup.9)OCOR.sup.10, CR.sup.9 R.sup.10, C(R.sup.9)OR.sup.10, C(OR.sup.9)OR.sup.10, or CH--CH.sub.2 (CO.sub.2 R.sup.11); or --G--A-- is --CR.sup.5 --CH.sub.2 -- where R.sup.5 is .dbd.CR.sup.7 XR.sup.8, .dbd.NOCR.sup.6 R.sup.7 XR.sup.8, .dbd.NOR.sup.11 or .dbd.NOCOR.sup.11 ; PA1 X is (CH.sub.2).sub.n, CH.dbd.CH, CH(OR.sup.20)CH.sub.2, or COCH.sub.2 ; PA1 n is 0, 1 or 2; PA1 R.sup.6 and R.sup.7 are independently selected from H, optionally substituted alkyl, alkenyl or alkynyl, halogen, NR.sup.9 R.sup.10, or R.sup.6 and R.sup.7 together with the carbon to which they are attached form an optionally substituted alkenyl or cycloalkyl group; PA1 R.sup.8 is CO.sub.2 R.sup.12, CN, COR.sup.12, CH.sub.2 OR.sup…
