The present invention relates to a group of polyheterocyclic compounds covered by the following formula: ##STR1## wherein each of X.sub.1, X.sub.2, X.sub.3, and X.sub.4, independently, is O, S, NH, or N(C.sub.1-6 alkyl), but one of them must be O, NH, or N(C.sub.1-6 alkyl); each of R.sub.1, R.sub.2, R.sub.5, and R.sub.6, independently, is H or a substituent (e.g., halogen, CN, NO.sub.2, or C.sub.1-4 haloalkyl), but at least one of them must be a substituent; each of R.sub.3 and R.sub.4, independently, is H, C.sub.1-6 alkyl, CHO, CH.sub.2 OH, or CH.sub.2 NH.sub.2 ; and each of m and n, independently, is 0 or 1.
本发明涉及一组多杂环化合物,其公式如下所示:##STR1##其中X.sub.1、X.sub.2、X.sub.3和X.sub.4分别独立地为O、S、NH或N(C.sub.1-6烷基),但其中一个必须为O、NH或N(C.sub.1-6烷基);R.sub.1、R.sub.2、R.sub.5和R.sub.6分别独立地为H或取代基(例如,卤素、CN、NO.sub.2或C.sub.1-4卤代烷基),但其中至少一个必须为取代基;R.sub.3和R.sub.4分别独立地为H、C.sub.1-6烷基、CHO、CH.sub.2OH或CH.sub.2NH.sub.2;m和n分别独立地为0或1。
