  Convenient synthesis of novel geiparvarin analogs with potential anti-cancer activity via click chemistry

  摘要：

  Based on the advantages of natural products in new anti-cancer drug development, we synthesized a series of novel benzopyran-4-one derivatives and evaluated their in vitro anti-cancer activities. The bioassays showed that the majority of the resultant compounds exerted anti-tumor effect against six human cancer cell lines to various extents, which supported the rationale of the design. Compound 5s exhibited highest potency of all the synthesized compounds. (C) 2012 Elsevier Masson SAS. All rights reserved.

  An I2/DTBP-promoted (3+2) cycloaddition reaction of 2-aminopyridines and chromones is reported. The work provides a simple and efficient approach to access imidazopyridines scaffold in moderate to good yields. I2/DTBP as an initiator and oxidant was used to realize the tandem (3+2) cycloaddition/oxidative aromatization. Available starting materials, excellent functional-group tolerance, potential drug
