Claims13
A compound of formula (I) ##STR8## or a salt thereof, wherein R.sup.1 represents a methyl, ethyl or isopropyl group;
- R.sup.2 represents a hydrogen atom, a C.sub.1-8 alkyl group or a C.sub.3-8 alkenyl group and the group .dbd.NOR.sup.2 is in the E-configuration;
- OR.sup.3 is a substituted hydroxy group which has a formula --OCSOR.sup.4, where R.sup.4 is an aliphatic, araliphatic, or aromatic group;
- a group --OSO.sub.2 R.sup.6, where R.sup.6 is C.sub.1-4 alkyl or C.sub.6-10 aryl;
- a group OCO(CH.sub.2).sub.n CO.sub.2 R.sup.7 where R.sup.7 is a hydrogen atom or an aliphatic, araliphatic or aromatic group, and n represents 0, 1 or 2;
- or a group OCONR.sup.8 R.sup.9, where R.sup.8 and R.sup.9 may each independently represent a hydrogen atom or a C.sub.1-4 alkyl group.
