  A two-step, one-pot method has been developed for the synthesis of 3-haloflavones from the corresponding flavones. The method uses Oxone® and potassium halide to produce the active molecular halogen in situ. The solvent (methanol) then participates in the reaction to afford the 2-methoxy-3-haloflavanone derivative. After adding sodium hydroxide, the corresponding 3-haloflavone product is obtained in

  已经开发了一种两步一锅法，用于从相应的黄酮合成3-卤代黄酮。该方法使用Oxone®和卤化钾原位生成活性分子卤素。然后，溶剂（甲醇）参与反应，得到2-甲氧基-3-卤代黄烷酮衍生物。加入氢氧化钠后，以良好至优异的产率获得相应的3-卤黄酮产物。该方法提供了从相同的黄酮起始原料方便地合成3-氯，3-溴和3-碘黄酮的方法。

  required synthesis of substituted flavones on large scale. Currently there are number of methods available to synthesize flavones, among them Baker Venkatraman strategy represents the most convenient route from 2hydroxy acetophenone. In this method, acid induced dehydrative cyclisation of 1,3 ( diaryl diketones ) obtained by intramolecular Claisen condensation of Ο benzoyl acetophenone to flavones in 75%

  催化量的FeCh影响取代的1(2羟基苯基)3苯基1、3丙二醇以高产率平滑转化为相应的黄酮。简介 : 黄酮是最丰富、最重要的黄酮类化合物，具有广泛的生物活性。最近对黄酮的兴趣源于它们抑制逆转录病毒转录酶的能力以及它们抑制蛋白质酪氨酸激酶和丝氨酸/苏氨酸激酶的能力。我们对研究黄酮作为醛糖还原酶抑制剂的兴趣需要大规模合成取代的黄酮。目前有多种方法可用于合成黄酮，其中 Baker Venkatraman 策略代表了从 2-羟基苯乙酮合成最便捷的路线。在该方法中，酸诱导脱水环化 1，3（二芳基二酮）通过 Ο 苯甲酰基苯乙酮分子内克莱森缩合得到黄酮，产率为 75%。上述脱水环化的最新进展包括在 MW 辐射下使用 Amberlyst 15、Co(Sulpr) OH、Br2/CHCl3、EtOH/HCl、粘土、NaOAc/AcOH 和 H2SO4。这些程序在操作简单性、反应时间、产率和试剂成本方面受到影响

  Although some progress has been reported on structure-activity relationships (SARs) for inhibitors of mammalian P-glycoprotein MDR efflux pumps, there is almost nothing in the literature regarding SARs for inhibitors of any bacterial efflux pump. Indeed, only a few of these have been described. Our discovery of a potent naturally occurring flavonolignan inhibitor of the NorA MDR pump of Staphylococcus aureus provided a structural foundation upon which SARs could be assessed via synthetic analogues. Several flavonolignans were prepared which proved to have greater potency than the natural isolate, 5'-methoxyhydnocarpin-D, while others showed decreased potency. Surprisingly, some simple alkylated flavones also were quite active MDR pump inhibitors. Variability of activity among the compounds tested was sufficient so that at least some SARs could be postulated and compared with those known for P-glycoprotein.
