  通过配体辅助卤化物交换实现芳基羧酸的钯催化脱羰碘化

  摘要：

  我们报道了一种高效且广泛适用的钯催化碘化方法，通过原位活化酰基氯并形成鏻盐，对廉价且丰富的芳基和乙烯基羧酸进行碘化。使用 1-碘丁烷作为碘化物源，与碱和脱氧氯化试剂结合使用，可以在 Pd/Xantphos 催化下获得各种芳基和乙烯基碘化物，包括复杂的药物样支架。化学计量实验和动力学分析表明了一种独特的机制，涉及 C−P 还原消除以形成 Xantphos 氯化鏻，随后通过外球亲核取代引发不寻常的卤素交换。

  Discovery of N-[(3R)-1-Azabicyclo[2.2.2]oct-3-yl]furo[2,3-c]pyridine-5-carboxamide, an Agonist of the α7 Nicotinic Acetylcholine Receptor, for the Potential Treatment of Cognitive Deficits in Schizophrenia:  Synthesis and Structure−Activity Relationship

  摘要：

  N-[(3R)-1-Azabicyclo[2.2.2] oct-3-yl] furo[2,3-c]pyridine-5-carboxamide (14, PHA-543,613), a novel agonist of the alpha 7 neuronal nicotinic acetylcholine receptor (alpha 7 nAChR), has been identified as a potential treatment of cognitive deficits in schizophrenia. Compound 14 is a potent and selective alpha 7 nAChR agonist with an excellent in vitro profile. The compound is characterized by rapid brain penetration and high oral bioavailability in rat and demonstrates in vivo efficacy in auditory sensory gating and, in an in vivo model to assess cognitive performance, novel object recognition.
