The synthesis of several new heterocyclic structural analogs of the natural antimitotic agent allocolchicine is reported. As a key step an intramolecularPd-catalyzedC–Harylationreaction was used to close the seven-membered ring fused with two electron-rich aryl fragments. The stereostructure of the target compounds was determined by X-ray crystal analysis. The primary biological assessment of the
