  New synthetic approaches to estrogen receptor modulators: imidazo[1,2-a]pyridines

  摘要：

  Constrained triarenes have been important templates for selective modulation of the estrogen receptor (ER). For our ER program. we sought an unexplored, synthetically accessible heterocyclic template capable of bearing a broad range of pharmacophores. Traditional approaches to these therapeutics such as raloxifene have relied on an alkoxy moiety to link the arene-based scaffold to the modulating amine group. Alternatively, aryl halide-mediated introduction of alkylene or aryl side chains has not been studied extensively. The synthetic incorporation of pharmacophoric side chains that are carbon-linked to a novel imidazopyridine-based ER recognition motif is disclosed. (C) 2003 Elsevier Science Ltd.
