  Discovery of +(2-{4-[2-(5,6,7,8-tetrahydro-1,8-naphthyridin-2-yl)ethoxy]phenyl}-cyclopropyl)acetic acid as potent and selective αvβ3 inhibitor: Design, synthesis, and optimization

  摘要：

  The integrin alpha(v)beta(3) is expressed in a number of cell types and is thought to play a major role in several pathological conditions. Various small molecules that inhibit the integrin have been shown to suppress tumor growth and retinal angiogenesis. The tripeptide Arg-Gly-Asp (RGD), a common binding motif in several ligands that bind to alpha(v)beta(3), has been depeptidized and optimized in our efforts toward discovering a small molecule inhibitor. We recently disclosed the synthesis and biological activity of several small molecules that did not contain any peptide bond and mimic the tripeptide RGD. The phenethyl group in one of the lead compounds was successfully replaced with a cyclopropyl moiety. The new lead compound was optimized for potency, selectivity, and for its ADME properties. We describe herein the discovery, synthesis, and optimization of cyclopropyl containing analogs that are potent and selective inhibitors of alpha(v)beta(3). (c) 2007 Elsevier Ltd.

  正式的均一纳扎罗夫和活化环丙烷的其他环化反应

  摘要：

  纳扎罗夫对二乙烯基酮的环化作用可得到环戊烯酮。用环丙烷取代乙烯基之一会导致形成正式的正己-纳扎罗夫合成环己烯酮的过程。与纳扎罗夫反应相反，乙烯基环丙基酮的环化是一个逐步过程，通常需要苛刻的条件。本文中，我们描述了两种不同的方法，可进一步极化乙烯基-环丙基酮的三元环，从而在温和的催化条件下进行正式的均一纳扎罗夫反应。在第一种方法中，将酯基α引入到环丙烷的羰基上，反应速率提高了十倍以上，这使我们可以将反应范围扩展到β位置的非电子富芳基供体取代基环丙烷上的羰基。在这种情况下，使用手性路易斯酸催化剂可以实现不对称诱导的原理证明。在第二种方法中，将杂原子（尤其是氮）引入β到环丙烷的羰基上。在这种情况下，当乙烯基被吲哚杂环取代时，反应特别成功。对于游离吲哚，使用铜催化剂观察到了吲哚C3位置的正式均一纳扎罗夫环化反应。相反，使用布朗斯台德酸催化剂观察到在N1位置发生了新的环化反应。两种反应均用于天然生物

• Radical-Cation Vinylcyclopropane Rearrangements by TiO₂ Photocatalysis

  Radical cation vinylcyclopropane rearrangements by TiO2 photocatalysis in lithium perchlorate/nitromethane solution are described. The reactions are triggered by oxidative single electron transfer, which is followed by immediate ring-opening of the cyclopropanes to generate distonic radical cations as unique reactive intermediates. This approach can also be applied to vinylcyclobutane, leading to the

  描述了在高氯酸锂/硝基甲烷溶液中通过TiO2光催化进行的自由基阳离子乙烯基环丙烷重排。该反应由氧化性单电子转移触发，然后环丙烷立即开环以生成作为唯一反应性中间体的二甲苯基阳离子。这种方法也可以应用于乙烯基环丁烷，从而构建六元环。在初步机理研究的基础上，提出了通过二阶自由基阳离子的逐步机理，并得到密度泛函理论计算的支持。

  The first catalytic method for the cyclization of vinyl-cyclopropyl ketones (formal homo-Nazarov reaction) is reported. Starting from activated cyclopropanes, heterocyclic, and carbocyclic compounds were obtained under mild conditions using Bronsted acid catalysts. Preliminary investigation of the reaction mechanism indicated a stepwise process.

  Replacing one of the vinyl groups by a cyclopropane leads to a formal homo‐Nazarov process for the synthesis of cyclohexenones. In contrast to the Nazarov reaction, the cyclization of vinyl‐cyclopropyl ketones is a stepwise process, often requiring harsh conditions. Herein, we describe two different approaches for further polarization of the three‐membered ring of vinyl‐cyclopropyl ketones to allow the
