Compounds of the general formula: ##STR1## wherein X represents halogen or trifluoromethyl; R.sup.1 and R.sup.2, independently represent hydrogen or lower alkyl; R.sup.3, R.sup.4 and R.sup.5, which may be the same or different, each represent hydrogen, lower alkyl, lower alkenyl, lower alkynyl, lower alkanoyl, lower alkenoyl, C.sub.7-16 aralkyl or C.sub.6-10 aryl or a 5-9 membered unsaturated or aromatic heterocyclic ring; one or both of R.sup.4 and R.sup.5 may also represent aroyl groups; Z represents an oxygen atom or a sulfur atom or oxide thereof or a group NR.sup.6 (wherein R.sup.6 is as defined for R hereinafter or represents the group COR.sup.7 in which R.sup.7 represents hydrogen or optionally substituted aryl, heterocyclic, aralkyl, lower alkyl or lower alkoxy group; and R represents a C.sub.6-10 carbocyclic aromatic group or a heterocyclic group containing a 5-9 membered unsaturated or aromatic heterocyclic ring which ring contains one or more heteroatoms selected from O, N and S and optionally carries a fused ring which carbocyclic or heterocyclic group may carry one or more C.sub.1-4 alkyl or phenyl groups said groups being optionally substituted; and where acid or basic groups are present, the salts thereof are useful in combating abnormal cell proliferation. The compounds of the invention are prepared by inter alia alkylation, ring closure and oxidation.
