We developed an efficient method for synthesis of substituted N-benzoylindole via Pd(II)-catalyzed C-H functionalization of substituted N-(2-allylphenyl)benzamide. The reaction showed a broad substrate scope (including N-acetyl and N-Ts substrates) and substituted indoles were obtained in good to excellent yields. The most distinctive feature of this method lies in the high selectivity for N-benzoylindole over benzoxazine, and this is the first example of Pd(II)-catalyzed synthesis of substituted N-benzoylindole. Notably, this new method was applied for the synthesis of key intermediate of indomethacin.

The invention relates to an indole compound and synthesizing and application methods thereof. The indole compound is prepared by selecting specific substituent groups. Experiments find that the indolecompound can achieve good inhibiting effects on prostatic cancer, good in drug-resistance-proofness and low in side effects when applied as an anti-cancer drug; besides, the synthesizing method of the indole compound comprises subjecting a compound with the structure shown as the formula (II), palladium acetate, benzoquinones and organic acids to reaction in solvent to obtain the indole compoundwith the structure shown as the formula (I). Experiment results show that the synthesizing method of the indole compound is low in requirements on substrate and high in product yield.
