A facile method to synthesize 3‐halobenzo‐heterocyclic‐2‐carbonylcompounds is described. Mechanistic studies suggested that a halo‐cyclization process, which generated the unstable spiro‐acetal transition state and readily convertible to the corresponding carbonylcompound might be involved. Diverse 3‐halobenzo‐heterocyclic‐2‐carbonylcompounds could be synthesized with up to 95 % yield in mild conditions

A series of novel indole-imidazole derivatives have been prepared and evaluated in vitro on the aromatase inhibitory activities. The results suggested that proton or a small electron-withdrawing group at para-position of the phenyl ring would enhance the inhibitory activities and any bulky group should be avoided in order to keep a relative small volume for this kind of molecules.
