  Synthesis and biological evaluation of substituted 2-sulfonyl-phenyl-3-phenyl-indoles: a new series of selective COX-2 inhibitors

  摘要：

  A new series of substituted 2-sulfonyphenyl-3-phenyl-indole derivatives were synthesized and evaluated for their ability to inhibit COX-2 and COX-lenzymes. Most of the compounds synthesized were found to be highly potent and selective inhibitors of COX-2. This work led to the discovery of 2-aminosulfonylphenyl-3-phenyl-indole 5a which possesses higher activity and selectivity for COX-2 than Celecoxib both in vitro and in vivo.

  COX-1/COX-2 inhibitors based on the methanone moiety

  摘要：

  This paper focuses on the synthesis and the in vitro testing of dual COX-1/COX-2 inhibitors. Starting from structures of non-steroidal anti-inflammatory drugs (NSAIDs) the diaryl methanone element was chosen as a lead. Modifications were carried out on this scaffold to obtain potent inhibitors of the COX enzymes. The N-(2-aroylphenyl)sulphonamides and -amides were studied in detail, and to consolidate the data evaluated the corresponding 3- and 4-regioisomers were also investigated. The potency and the enzyme selectivity were varied by structural modifications of the lead. (C) 2002 Published by Editions scientifiques et medicales Elsevier SAS.

  Ru(II)-catalyzed intermolecular ortho-C–H amidation of weakly coordinating aromatic ketones with sulfonyl azides is reported. The developed reaction protocol can be extended to various substituted aromatic ketones to afford a wide range of desired C–N bond formation products in good yields.

  on NIS (N‐iodosuccinimide)‐mediated cycloisomerization reactions of 1‐(2′‐anilinyl)prop‐2‐yn‐1‐ols to gem‐3‐(diiodomethyl)indolin‐2‐ones and 2‐(iodomethylene)indolin‐3‐ones has been developed. The reactions were shown to be chemoselective, with secondary and tertiary alcoholic substrates exclusively giving the 3‐ and 2‐oxindole products, respectively. In the case of the latter, the transformation features

  Don't cross me! 2‐Alkynyl indoles were prepared efficiently by the AgOTf‐catalyzed tandem heterocyclization/alkynylation of 1‐(2‐tosylamino)aryl)but‐2‐yne‐1,4‐diols under mild conditions (see scheme). The attractiveness of this approach lies in the fact that both the indole ring and alkyne side chain of the N‐heterocycle are sequentially formed from low cost, readily available, and ecologically benign

  不要越过我！在温和的条件下，通过AgOTf催化1-（2-甲苯磺酰基氨基）芳基）-2-炔-1,4-二醇的串联杂环化/炔基化反应，可以高效地制备2-炔基吲哚。这种方法的吸引力在于，N-杂环的吲哚环和炔烃侧链都是由低成本，易得且生态友好的起始原料依次形成的。它也提供了不基于交叉偶联策略而获得此类具有合成价值的化合物的第一条途径。

  excellent yields up to 99% and with complete chemoselectivity. The mechanism is suggested to involve cop- per(II)-mediated dehydration of the homoallylic amino alcohol. Protonation of the resultant cop- per(II)-activated aminodiene is then thought to trigger subsequent intramolecular hydroamination to give the partially hydrogenated nitrogen heterocycle.

  描述了一种新的高效合成路线，该路线依赖于温和且操作简便的条件下，三氟甲磺酸铜（II）催化均烯丙基氨基醇分子内胺化，生成反式-2,5-二氢-1 H-吡咯和1,2-二氢喹啉。对于反应导致的反式-2,5-二氢-1- ħ -吡咯产物，的52-83％的产率与沿反式选择性高达> 99：1个博士和EE值高达97％是从对映体富集完成1-（甲苯磺酰氨基）戊-4-烯-2-醇，ee范围为91–99％。不需要惰性和无湿气的条件，涉及1- [2-（甲苯磺酰基氨基）苯基] but-3-en-1-ols的反应可提供相应的1,2-二氢喹啉产物，收率高达99％，且完全的化学选择性。建议该机制涉及铜（II）介导的均烯丙基氨基醇的脱水。然后认为所得的经铜（II）活化的氨基二烯的质子化会触发随后的分子内加氢胺化反应，从而产生部分氢化的氮杂环。
