  摘要：

  A new series of N-(1H-tetrazol-5-yl)-6-phenyl-2-pyridinecarboxamides was prepared to determine the effects of substituents on the benzene and pyridine rings on antiallergic activity in the rat passive cutaneous anaphylaxis (PCA) assay after oral administration. One member of this series, N-(1H-tetrazol-5-yl)-4-methyl-6-[4-(methylamino)-phenyl]-2- pyridinecarboxamide (231), has an ED50 value of 0.8 mg/kg po and is 85 times more potent than disodium cromoglycate (DSCG) on intravenous administration. Further evaluation of 231 as a clinically useful antiallergic agent is in progress.

  challenging when oxygen is used as the oxidant. Here, we report a palladium complex bearing a bidentate pyridine/pyridone ligand that efficiently catalyzes this reaction at ring positions adjacent to carboxylic acids. Infrared, x-ray, and computational analysis support a possible role of ligand tautomerization from mono-anionic (L,X) to neutral (L,L) coordination in the catalytic cycle of aerobic carbon–hydrogen

  当使用氧气作为氧化剂时，使用过渡金属催化剂对芳基碳氢键进行羟基化已被证明具有挑战性。在这里，我们报告了一种钯配合物，它带有双齿吡啶/吡啶酮配体，可在与羧酸相邻的环位置有效地催化该反应。红外、X 射线和计算分析支持从单阴离子 (L,X) 到中性 (L,L) 配位的配体互变异构在好氧碳氢羟基化反应的催化循环中的可能作用。由杂环决定的传统位点选择性被这种催化剂推翻，从而允许在以前无法接近的位点对药物感兴趣的化合物进行后期修饰。
