Abstract

The invention provides an oxacyclononadiene derivative, a stereochemical isomer thereof, a solvate thereof or a pharmaceutically acceptable salt thereof. The oxacyclononadiene derivative can achieve arelatively good anti-tumor effect. The invention also provides a preparation method of the oxacyclononadiene derivative. The preparation method comprises the following steps: adding a palladium catalyst into a reactor, then dissolving dicyanodiene and alkenyl cyclic carbonate into a solvent, adding the formed solution into the reactor under the protection of argon, carrying out a reaction for 20-30 hours at a temperature of 15-22 DEG C, and performing concentrating and purifying to obtain the oxacyclononadiene derivative. The preparation method is simple in process, high in yield and convenient for industrial popularization and application. In addition, the invention also provides a pharmaceutical composition with the oxacyclononadiene derivative as an active ingredient and application ofoxacyclononadiene in preparation of antitumor drugs.
