英文摘要: Imidazo[1,2-a]pyridines is an important class of N-containing fused heterocyclic compounds and their structures are similar to those of indoles and azaindoles. Their core ring system exhibit excellent antiviral, hypnotic, anti-inflammatory and antiulcer activities, especially antitumor activities. This program is aiming to design and synthesize imidazo[1,2-a]pyridine derivatives, and find the lead compounds. The work includes the following: (1) transition-metal catalyzed carbon-carbon bonds formation reaction to synthesize imidazo[1,2-a]pyridine derivatives with new carbon-carbon bonds, including alkyenylation, carbonylation, arylation and alkylation; (2) transition-metal catalyzed carbon-heteroatom bond formation reaction to synthesize imidazo[1,2-a]pyridine derivatives with new carbon-heteroatom bonds, including thiolation, amidation, acetoxylation and halogenation; (3) The antitumor activities of these compounds will be screened. With the help of drug design by computer-aided, the leading compound will next be designed and synthesized, and the structure-activity relationship will be discussed.
