or additionally represents cyclopropyl, cyclopentyl, cyclohexyl, cyclohexenyl, cyclopropylmethyl, cyclopropylethyl, cyclohexylmethyl, cyclohexylethyl or cycloheptyl, which are in each case optionally monosubstituted, disubstituted or trisubstituted by identical or different substituents from the group consisting of fluorine, chlorine, methyl, ethyl and cyano;
or represents benzyl, phenylethyl or phenyl,
X represents oxygen or sulphur,
Y represents oxygen or sulphur, and
R.sup.3 and R.sup.4, independently of each other, each represents hydrogen, alkyl with 1 to 4 carbon atoms, phenyl or benzyl.
