  卤素原子参与指导缩醛取代反应的立体化学结果

  摘要：

  α-卤代缩醛的亲核加成通过氧碳鎓离子中间体进行，其中碳-卤素键可以采用假轴位置或假赤道位置。当卤素原子位于缩醛的 C-2 处时，通常会观察到反式选择性，因为涉及假轴碳-卤素键的超共轭相互作用稳定了氧碳鎓离子中间体。

  The present invention describes novel nitrosated and/or nitrosylated cyclooxygenase 2 (COX-2) inhibitors and novel compositions comprising at least one nitrosated and/or nitrosylated cyclooxygenase 2 (COX-2) inhibitor, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase, and/or optionally, at least one therapeutic agent, such as, steroids, nonsteroidal antiinflammatory compounds (NSAID), 5-lipoxygenase (5-LO) inhibitors, leukotriene B 4 (LTB 4 ) receptor antagonists, leukotriene A 4 (LTA 4 ) hydrolase inhibitors, 5-HT agonists, 3-hydroxy-3-methylglutaryl coenzyme A (HMGCoA) inhibitors, H antagonists, antineoplastic agents, antiplatelet agents, decongestants, diuretics, sedating or non-sedating anti-histamines, inducible nitric oxide synthase inhibitors, opioids, analgesics, Helicobacter pylori inhibitors, proton pump inhibitors, isoprostane inhibitors, and mixtures thereof. The present invention also provides novel compositions comprising at least one parent COX-2 inhibitor and at least one nitric oxide donor, and, optionally, at least one therapeutic agent. The present invention also provides kits and methods for treating inflammation, pain and fever; for treating and/or improving the gastrointestinal properties of COX-2 inhibitors; for facilitating wound healing; for treating and/or preventing renal toxicity; and for treating and/or preventing other disorders resulting from elevated levels of cyclooxygenase-2.
