  使用碳硼烷催化剂进行芳香卤化

  摘要：

  卤代芳烃一直是现代有机化学领域中的一类重要化学品，因为卤化物官能团提供了许多可能的转化。使用分子卤素和路易斯/布朗斯台德酸活化剂的经典亲电芳香族卤化仍然是一种有前途的合成工具；然而，它存在操作困难、选择性低和官能团耐受性有限的问题。我们在此介绍基于碳硼烷的路易斯碱催化剂，用于使用卤代琥珀酰亚胺进行芳族卤化。所开发的反应体系易于应用于药物分子的后期功能化和多卤代芳烃的高效合成。 β-碳硼烷支架最适合催化，并且通过装饰簇顶点进行可能的微调对于调节卤物种的电子性质以最大化催化性能非常重要。

  The smoothened (Smo) receptor mediates Hh signalling. In the present study, we synthesised a series of novel tetrahydrothieno[3,2-c]pyridine derivatives using a scaffold hopping strategy. Compounds with this novel scaffold demonstrated promising Hh and Smo inhibition, indicating that this novel scaffold can serve as a starting point for further optimisation.
