    <p>In the present paper, a simple, highly efficient, and environmentally friendly protocol was proposed for the Knoevenagel condensation reaction of aromatic aldehydes using Meldrum’s acid (2,2-dimethyl-4,6-dioxo-1,3-dioxane) with bentonite as an available non-toxic mineral catalyst exposed to aqueous media under green conditions. Together with the substitution protocol of electron-donating or -withdrawing groups, all reactions were finalized from 5 to 120 min in water at 90°C. With regard to such reactions, the purification of columns on products was not a requirement. Considering the environmental aspect, use of water as a green solvent, utilization of a reusable catalyst, simple work-up process and steps, as well as rapid reaction times were taken into account as some characteristics of these chemical reactions.</p></sec></div> <div class="value-text ch">在本文中,我们提出了一种简单、高效且环保的协议,用于在水相介质下进行芳香醛的Knoevenagel缩合反应。该反应使用Meldrum酸(2,2-二甲基-4,6-二氧杂-1,3-二氧环己烷)作为可用的非有毒矿物催化剂,并与膨润土相结合。在90°C的水中,所有反应在5到120分钟内完成,无需对产物进行柱层析纯化。考虑到环境因素,使用水作为绿色溶剂,利用可重复使用的催化剂,简化了工作过程和步骤,以及快速的反应时间,都是这些化学反应的一些特点。</div> </div> </li> <li class="feature-list-item"> <div class="content-title">Oxidative and Enantioselective Cross-Coupling of Aldehydes and Nitromethane Catalyzed by Diphenylprolinol Silyl Ether</div> <div class="value"> <div class="value-text"> <span>作者:</span>Yujiro Hayashi、Takahiko Itoh、Hayato Ishikawa </div> <div class="value-text"> <span>DOI:</span>10.1002/anie.201006885 </div> <div class="value-text"> <span>日期:</span>2011.4.18 </div> <div class="value-text en">Synthetically important β‐substituted γ‐nitro <span style='color:#ff0000'>aldehydes</span> have been synthesized with excellent <span style='color:#ff0000'>enantioselectivity</span> by the cross‐coupling reaction of β‐aryl substituted <span style='color:#ff0000'>aldehydes</span> or γ,δ‐unsaturated <span style='color:#ff0000'>aldehydes</span> and nitromethane using 2,3‐dichloro‐5,6‐dicyanoquinone (DDQ) and diphenylprolinol silyl <span style='color:#ff0000'>ether</span> as an oxidant and catalyst, respectively (see scheme; TMS=trimethylsilyl).</div> <div class="value-text ch">使用2,3-二氯-5,6-二氰基醌(DDQ)通过β-芳基取代的醛或γ,δ-不饱和醛与硝基甲烷的交叉偶联反应合成了具有重要对映选择性的重要合成的重要β-取代的γ-硝基醛。 )和二苯基脯氨醇甲硅烷基醚分别作为氧化剂和催化剂(请参见方案; TMS =三甲基甲硅烷基)。</div> </div> </li> <li class="feature-list-item"> <div class="content-title">Stereoselective Sequential Spirocyclopropanation/Cloke–Wilson Rearrangement Reactions for Synthesis of <i>trans</i>-β,γ-Disubstituted γ-Butyrolactones Using Alkylidene Meldrum’s Acid and Benzyl Halides</div> <div class="value"> <div class="value-text"> <span>作者:</span>Minli Zhang、Tong Li、Chaoxing Cui、Xixi Song、Junbiao Chang </div> <div class="value-text"> <span>DOI:</span>10.1021/acs.joc.9b02978 </div> <div class="value-text"> <span>日期:</span>2020.2.21 </div> <div class="value-text en">spirocyclopropanation/Cloke-Wilson <span style='color:#ff0000'>rearrangement</span> reactions have been developed to synthesize γ-butyrolactones using alkylidene Meldrum's acids and benzyl <span style='color:#ff0000'>halides</span>.
