Compounds of the general formula: ##STR1## (wherein X represents a halogen atom or a trifluoromethyl group; R.sup.1 and R.sup.2 independently represent a hydrogen atom or a lower alkyl group; Z is --O--, --S--, --SO--, --SO.sub.2 -- or the group --NR.sup.4 -- wherein R.sup.4 is as defined for R hereinafter or represents the group COR.sup.5 in which R.sup.5 represents a hydrogen atom or an optionally substituted aryl, heterocyclic, aralkyl, lower alkyl or lower alkoxy group; 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; or, where Z represents the group >NR.sup.4, the group --ZR may represent a heterocyclic ring optionally carrying a fused ring and/or optionally substituted as defined for R; and R.sup.3 represents a hydrogen atom or a lower alkyl, lower alkenyl, lower alkynyl, lower alkanoyl, lower alkenoyl, C.sub.7-16 aralkyl or C.sub.6-10 arly group or a 5-9 membered unsaturated or aromatic heterocyclic ring); 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.
通式为:##STR1## 的化合物(其中X代表卤素原子或三氟甲基基团;R.sup.1和R.sup.2分别代表氢原子或较低的烷基基团;Z为--O--,--S--,--SO--,--SO.sub.2 --或基团--NR.sup.4 --其中R.sup.4如下所定义或代表基团COR.sup.5,其中R.sup.5代表氢原子或可选择取代的芳香族、杂环、芳基烷基、较低的烷基或较低的烷氧基团;R代表C.sub.6-10碳环芳族或含有5-9个成员的不饱和或芳香杂环环,该环含有O、N和S中选定的一个或多个杂原子,并且可选择携带一个融合环的碳环或杂环基团,该碳环或杂环基团可以携带一个或多个C.sub.1-4烷基或苯基基团,这些基团可选择取代;或者,Z代表基团>NR.sup.4时,基团--ZR可以代表一个可选择携带一个融合环和/或可选择取代的杂环环,如R所定义;R.sup.3代表氢原子或较低的烷基、较低的烯基、较低的炔基、较低的烷酰基、较低的烯酰基、C.sub.7-16芳基烷基或C.sub.6-10芳基基团或一个5-9成员的不饱和或芳香杂环环);并且,如有酸性或碱性基团存在,其盐;在对抗异常细胞增殖方面是有用的。该发明的化合物是通过烷基化、环闭合和氧化等方法制备的。
