The present invention relates to a group of polyheterocyclic compounds covered by the following formula:
wherein each of X1, X2, X3, and X4, independently, is O, S, NH, or N(C1-6alkyl), but one of them must be O, NH, or N(C1-6 alkyl); each of R1, R2, R5, and R6, independently, is H or a substituent (e.g., halogen, CN, NO2, or C1-4 haloalkyl), but at least one of them must be a substituent; each of R3 and R4, independently, is H, C1-6 alkyl, CHO, CH2OH, or CH2NH2; and each of m and n, independently, is 0 or 1.
本发明涉及一组由下式涵盖的多杂环化合物:
其中X1、X2、X3和X4各自独立地为O、S、NH或N(C1-6烷基),但其中一个必须为O、NH或N(C1-6烷基);R1、R2、R5和R6各自独立地为H或取代基(如卤素、CN、NO2或C1-4卤代烷基),但其中至少一个必须为H或取代基、R3和R4各自独立地为H、C1-6烷基、CHO、CH2OH或CH2NH2;m和n各自独立地为0或1。
