  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

  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
• Substituted cinnamic anhydrides act as selective inhibitors of acetylcholinesterase
  作者：Josephine M. Gießel、Immo Serbian、Anne Loesche、René Csuk

  DOI：10.1016/j.bioorg.2019.103058

  日期：2019.9

  Cinnamic anhydrides have been shown to be more than reactive reagents, but they also act as inhibitors of the enzyme acetylcholinesterease (AChE). Thus, out of a set of 33 synthesised derivatives, several of them were mixed type inhibitors for AChE (from electric eel). Thus, (E)-3-(2,4-dimethoxyphenyl)acrylic anhydride (2c) showed Ki = 8.30 ± 0.94 µM and Ki' = 9.54 ± 0.38 µM, and for (E)-3-(3-chlorophenyl)acrylic

  肉桂酸酐已被证明比反应性试剂更重要，但它们也可作为乙酰胆碱酯酶（AChE）的抑制剂。因此，在一组33种合成衍生物中，其中几种是AChE的混合型抑制剂（来自鳗鱼）。因此，对于（E）-3-（3-氯苯基）丙烯酸，（E）-3-（2，4-二甲氧基苯基）丙烯酸酐（2c）的Ki ＝ 8.30±0.94μM，Ki’＝ 9.54±0.38μM。酸酐（2u）的Ki = 8.23±0.93 µM，Ki'= 13.07±0.46 µM。这些化合物虽然对许多人类细胞系无细胞毒性，但它们对AChE却表现出前所未有的且值得注意的抑制作用，但对丁酰胆碱酯酶（BChE）却没有。

  Cinnamic acid and its derivatives are known for anti-tubercular activity. The present study reports the synthesis of cinnamic acid derivatives via bioisosteric replacement of terminal carboxylic acid with "oxadiazole". A series of cinnamic acid derivatives (styryl oxadiazoles) were designed and synthesized in good yields by reaction of substituted cinnamic acids (2, 15a-15s) with amidoximes. The synthesized
