Abstract

A compound of general formula ##STR1## wherein X represents a radical selected from the group consisting of one of the formulae ##STR2## in which R.sup.1 represents a radical selected from the group PA2 (a) a hydrogen atom, PA2 (b) an amino group, when X represents an --OR.sup.1 moiety, PA2 (c) an alkyl group having from 1 to 6 carbon atoms PA2 (d) an at most binuclear aryl group being unsubstituted or substituted by at most 3 substituents of the group halogen atoms, alkyl, alkoxy, halogenalkyl groups each having up to 4 carbon atoms, cycloalkyl groups having 3 to 6 carbon atoms, nitro and cyano groups; and PA1 R.sup.2 and R.sup.3, which may be the same or different, each represents a radical selected from the group PA2 (a) a hydrogen atom, PA2 (b) an alkyl group having from 1 to 6 carbon atoms, an unsubstituted cycloalkyl group having from 3 to 7 carbon atoms, such cycloalkyl group substituted by at most 3 substituents of the group hydroxy groups and alkoxycarbonyl groups having 1 to 4 carbon atoms, PA2 (c) an aralkyl group, a diaralkyl group each having 1 to 4 carbon atoms in the alkyl moiety and being unsubstituted or substituted in at least one of the radicals in the alkyl moie…
