制备方法与用途

概述

2-溴-3-氟-4-甲基吡啶是一种含有氟的吡啶衍生物。吡啶衍生物是一类重要的医药中间体，常作为甾族化合物、磺胺类、抗阻胺类及螺环酰胺类等药物的合成原料。含氟吡啶类化合物作为重要的一类吡啶衍生物，在有机合成和药物中间体合成中应用广泛。

尽管氟原子与氢原子的半径相近，但当分子中的氢原子被氟原子取代后，并不会显著改变该分子的立体构型。然而，由于氟原子具有很强的吸电子能力，会极大影响原有分子的电子性质。因此，含氟吡啶具有良好的稳定性和较大的介电各向异性，在医药领域尤其是合成抗癌药物和治疗心脑血管疾病的药物方面发挥着重要作用。

  Design and synthesis of pyridone inhibitors of non-nucleoside reverse transcriptase

  摘要：

  Next generation NNRTIs are sought which possess both broad spectrum antiviral activity against key mutant strains and a high genetic barrier to the selection of new mutant viral strains. Pyridones were evaluated as an acyclic conformational constraint to replace the aryl ether core of MK-4965 (1) and the more rigid indazole constraint of MK-6186 (2). The resulting pyridone compounds are potent inhibitors of HIV RT and have antiviral activity in cell culture that is superior to other next generation NNRTI's. (C) 2011 Elsevier Ltd.
