摘要:
A novel, sequential, palladium-catalyzed, cross-coupling reaction using N-tosylhydrazone and bromonitrobenzene derivatives followed by reductive cyclization has been developed. This transformation providing an efficient route to unexpected N-arylindole derivatives involves, in a one-pot reaction, the formation of one Csp(2)-Csp(2) bond and two Csp(2)-N bonds together with the cleavage of one Csp(2)-heteroatom bond. Evaluation of the biological activity led to the identification of compound 5a, which displays potent activity at nanomolar concentrations against human colon carcinoma cell line.
