Abstract:
A compound of formula (I) ##STR86##in whichR is an --NO.sub.2 group or an --NHR.sub.3 group,R.sub.3 being a hydrogen atom, a --COR.sub.4 group (where R.sub.4 is selected from the (C.sub.1 -C.sub.4)alkyl, aryl and aryl(C.sub.1 -C.sub.4)alkyl groups), a --COOR.sub.5, group (where R.sub.5 is selected from the (C.sub.1 -C.sub.4)alkyl and aryl(C.sub.1 -C.sub.4)alkyl groups), a --CONHR.sub.6 group, an --SO.sub.2 R.sub.6, group (where R.sub.6 is selected from the (C.sub.1 -C.sub.5)alkyl, aryl and aryl(C.sub.1 -C.sub.4)alkyl groups), or an --SO.sub.2 NR.sub.7 R.sub.8 group (where R.sub.7 and R.sub.8 are each, independently of each other, a hydrogen atom or a (C.sub.1 -C.sub.4)alkyl group or form with the nitrogen atom carrying them a morpholine group), an aryl(C.sub.1 -C.sub.4)alkyl group (the aryl group being unsubstituted or substituted with a halogen atom, a linear or branched (C.sub.1 -C.sub.5)alkyl group, a trifluoromethyl group, a cyano group, a (C.sub.1 -C.sub.4)alkoxycarbonyl group or a (C.sub.1 -C.sub.4)acylamino group), or a pyridyl(C.sub.1 -C.sub.4)alkyl group, or a thienyl(C.sub.1 -C.sub.4)alkyl group;R.sub.1 is a linear or branched (C.sub.1 -C.sub.4)alkyl group, a cyclo(C.sub.3 -C.sub.8)alkyl group, an aryl group (the aryl group being unsubstituted or substituted with a halogen atom, a linear or branched (C.sub.1 -C.sub.5)alkyl group, a trifluoromethyl group, a cyano group, a (C.sub.1 -C.sub.4)alkoxycarbonyl group or a (C.sub.1 -C.sub.4)acylamino group), an aryl(C.sub.1 -C.sub.4)alkyl group (the aryl component of the aryl(C.sub.1 -C.sub.4)alkyl group being unsubstituted or substituted with a halogen atom, a linear or branched (C.sub.1 -C.sub.5)alkyl group, a trifluoromethyl group, a cyano group, a (C.sub.1 -C.sub.4)alkoxycarbonyl group or a (C.sub.1 -C.sub.4)acylamino group), or a pyridyl or thienyl group;R.sub.2 is a hydrogen atom, a (C.sub.1 -C.sub.4)alkyl group, or an arylmethyl group;X is an oxygen or sulphur atom, or a --CH.sub.2 --, --SO.sub.2 or --NR.sub.1 -- group where R.sub.1 is as defined above; andY is a hydrogen atom or a linear or branched (C.sub.1 -C.sub.6)alkyl group.
