  摘要：

  通过将喹啉甲醛与β-苯胺基丙腈缩合，然后用胍处理，制备了一系列九个2,4-二氨基-5- [6-（或7-）喹啉基甲基]嘧啶。所有化合物在喹啉环的2-或4-位具有碱性或甲氧基取代基。所有6-喹啉基甲基衍生物均对大肠杆菌二氢叶酸还原酶（DHFR）具有高度抑制作用，前提是喹啉环中存在8位取代基。相对于脊椎动物对应物，在喹啉环的2位具有碱性取代基的那些化合物对细菌二氢叶酸DHFR也具有高度特异性。喹啉环氮上的质子化可能是特异性的原因。

  6-bromo-2-chloro-4-methylquinoline as a starting material. Since surprisingly little has been reported in the literature, the two synthetic steps to this compound were investigated. The synthesis involves a condensation between β-keto esters and 4-bromoaniline and the cyclization of the resulting anilides into 6-bromoquinolin-2(1H)-one, otherwise known as the Knorr reaction. The ¹H NMR monitoring of the first

  在我们关于传染病的工作过程中，我们被引导准备了6-溴-2-氯-4-甲基喹啉作为起始原料。由于文献中出人意料的报道很少，因此对该化合物的两个合成步骤进行了研究。该合成涉及β-酮酸酯和4-溴苯胺之间的缩合，以及将所得的苯胺环化成6-溴喹啉-2（1 H）-一，也称为克诺尔反应。该¹第一步的1 H NMR监测使我们能够优化导致苯胺的条件，而不会出现替代的巴豆酸酯。为了说明我们的发现的范围，制备了一些具有电子吸引基团的额外的酸酐。对它们环化的研究表明，这第二步支配着一些意想不到的空间效应。除了纠正该化学中的一些说法外，该研究还导致了三步制备6-溴-2-氯-4-甲基喹啉的步骤，而4-溴苯胺的总收率为48％。 酰化-环化-杂环-喹啉-碳正离子化

  The 80 MHz 1H NMR and 20 MHz 13C NMR spectra of five 4-methylcoumarins, six 4-methyl-2(1H)-quinolones and nine 3-methylbenzo[b]furans, including six new compounds, were fully assigned. Homonuclear 1H1H} NOEs and selective heteronuclear 13C1H} NOEs were measured after low-power pre-saturation of the methyl protons. Indirect, negative heteronuclear NOE enhancements were found in suitable three-spin systems of the 13C1H1H} type, and their magnitude was found to be dependent on ring size. The first examples of indirect, heteronuclear NOE enhancements on non-protonated carbons are described.
