A metal‐free and redox‐neutral method for Beckmannrearrangement employing inexpensive and readily available SO2F2 gas is described. The reported transformation proceeds at ambient temperature and is compatible with a wide range of sterically and electronically diverse aromatic, heteroaromatic, aliphatic and lignin‐like oximes providing amides in good to excellent yields. The reaction proceeds through
描述了使用便宜且易于获得的SO 2 F 2气体进行贝克曼重排的无金属和氧化还原中性方法。报道的转化在环境温度下进行,并且与各种空间和电子形式多样的芳族,杂芳族,脂族和木质素样肟兼容,可提供酰胺,产率高至优异。反应通过形成亚氨酰氟中间体进行,该中间体也可用于合成the。

The invention encompasses novel compounds of Formula I
or pharmaceutically acceptable salts thereof. These compounds are inhibitors of the microsomal prostaglandin E synthase-1 (mPGES-1) enzyme and are therefore useful to treat pain and/or inflammation from a variety of diseases or conditions, such as osteoarthritis, rheumatoid arthritis and acute or chronic pain. Methods of treating diseases or conditions mediated by the mPGES-1 enzyme and pharmaceutical compositions are also encompassed.
