• A Direct, Regioselective Palladium-Catalyzed Synthesis of N-Substituted Benzimidazoles and Imidazopyridines

  日期：2011.1

  Unsymmetric, N-substituted benzimidazoles and imidazopyridines can be prepared directly from 2-halonitroarenes and amides through Pd(TFA) 2 /(R)-BINAP-catalyzed cross-coupling and subsequent reductive aminocyclization. This sequence can be conducted by a one-pot procedure. The method is versatile and allows the straightforward, regioselective preparation of these important nitrogen heterocycles.

  不对称的、N-取代的苯并咪唑和咪唑并吡啶可以直接从 2-卤代硝基芳烃和酰胺通过 Pd(TFA) 2 /(R)-BINAP 催化的交叉偶联和随后的还原性氨基环化来制备。该序列可以通过一锅法进行。该方法用途广泛，可以直接、区域选择性地制备这些重要的氮杂环。

  Following the discovery of moderately potent antagonist activity platelet-activating factor (PAF) in 2-methyl-1-phenylimidazo[4,5-c]pyridine (2) (IC50 = 840 nM), 19 derivatives (3-21) were prepared which incorporated various lipophilic groups attached to the phenyl 4-position. Structure-activity relationships were evaluated where PAF antagonist activity was measured in vitro by determining the concentration
