The invention discloses a 4,5-disubstituted-1-hydro-pyrrole(2,3-f)quinoline-2,7,9-tricarboxylate compound and analogues or derivatives thereof. The structure of the compound is shown as a formula I, and the structural formula is as shown in the specification. In the formula, R1 and R4 are respectively and independently selected from the following atoms or groups: hydrogen, linear or branched C1-8 alkyl, deuterated linear or branched C1-8 alkyl, aralkyl or substituted aryl radical; R2 is independently selected from the following atoms or groups: halogen, linear or branched C1-8 alkoxy and deuterated linear or branched C1-8 alkoxy; and R3 is independently selected from the following atoms or groups: linear or branched C1-8 alkoxy and deuterated linear or branched C1-8 alkoxy. The compound can serve as a reaction intermediate for synthesizing PQQ (Pyrroloquinoline Quinone), and the oxidizing agent process adopting CAN in the PQQ synthesis in the conventional patent and literature is replaced. Therefore, the whole process is cheap and high-efficiency.
