Direct construction of N-C axial chirality via Pd-catalyzed atroposelective C-H olefination of N-arylindoles is reported. The crucial role of chiral amino acid as a cocatalyst in the regio- and stereocontrol has been disclosed. In this reaction, a wide range of arylindoles and functional alkenes could be well tolerated. Moreover, the practicality and synthetic value of this process were demonstrated by the divers and simple transformations of the products.

The invention discloses an efficient compounding method of a 3-substitued-benzo five-membered heterocycle-2-carbonyl compound. According to the method, a 3-substitued-benzo five-membered heterocycle-2-alcohol compound is subjected to a halogenated oxidation reaction by a halogenating reagent to generate the corresponding 3-substitued-benzo five-membered heterocycle-2-carbonyl compound. The efficient compounding method has the advantages that raw materials are easy to get, reaction conditions are mild, and reaction selectively and yield are high.

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.
