The invention discloses a novel chromone structure-containing pyrazole norcantharidin derivative, and a preparation method and an application thereof. The preparation method comprises the following steps of: introducing a pyrazole ring to the sites C5 and C6 in the norcantharidin structure by a 1,3-dipolar cycloaddition method, and reacting the norcantharidin with the pyrazole ring with chromone derivatives to import the chromone structure to synthesize a series of total 6 novel chromone structure-containing pyrazole norcantharidin derivatives; as a result, the activity of the norcantharidin is improved. The chromone structure-containing pyrazole norcantharidin derivatives provided by the invention are applied to the synthesis of anti-tumor drugs, and have wide application prospect.
