  Diarylspiro[2.4]heptenes as Orally Active, Highly Selective Cyclooxygenase-2 Inhibitors:  Synthesis and Structure−Activity Relationships

  摘要：

  A novel series of 5,6-diarylspiro[2.4]hept-5-enes was shown to provide highly potent and selective cyclooxygenase-2 (COX-2) inhibitors. A study of structure-activity relationships in this series suggests that 3,4-disubstituted phenyl analogs are generally more selective than 4-substituted phenyl analogs and that replacement of the methyl sulfone group on the B-phenyl ring with a sulfonamide moiety results in compounds with superior in vivo pharmacological properties, although with lower COX-2 selectivity, Several compounds have been shown to possess promising pharmacological properties in adjuvant-induced arthritis and edema analgesia models. The absence of gastrointestinal (GI) toxicity at 200 mpk of several selected compounds in rats and mice corresponds well with the weak potency for inhibition of COX-1 observed in the enzyme assay. Methyl sulfone 55 and sulfonamide 24 were shown to have superior in vivo pharmacological profiles, low GI toxicity, and good oral bioavailability and duration of action.

  A visible-light-driven and room temperature photo-Wolff-Kischner reaction of sulfur ylides and N-tosylhydrazones has been developed for the first time to provide modular access to alkene synthesis. The high functional group tolerance and broad substrate scope were demonstrated by more than 60 examples. Both E- and Z-olefinic stereochemistry in the products could be controlled with excellent stereoselectivity

  首次开发了硫叶立德和 N-甲苯磺酰腙的可见光驱动和室温光沃尔夫-基施纳反应，以提供烯烃合成的模块化途径。60 多个实例证明了高官能团耐受性和广泛的底物范围。产品中的 E- 和 Z- 烯烃立体化学都可以以优异的立体选择性进行控制。一系列机理研究支持该反应应该通过自由基 - 负离子交叉途径进行，具体涉及将光生硫叶立德自由基阳离子添加到 N-甲苯磺酰腙形成碳负离子和随后的沃尔夫-基施纳过程。
