Uncovering the Neglected Similarities of Arynes and Donor–Acceptor Cyclopropanes

Werz Daniel B.; Biju Akkattu T.

摘要

Abstract >Arynes and donor–acceptor (D–A) cyclopropanes are two classes of strained systems having the potential for numerous applications in organic synthesis. The last two decades have witnessed a renaissance of interest in the chemistry of these species primarily because of the mild and robust methods for their generation or activation. Commonly, arynes as easily polarizable systems result in 1,2‐disubstitution, whereas D‐A cyclopropanes as polarized systems lead to 1,3‐bisfunctionalization thereby showing striking similarities. Transformations with 1,2‐ and 1,3‐dipoles afford cyclic structures. With arynes, emerging four‐membered rings as intermediates might react further, whereas the analogous five‐membered rings obtained from D–A cyclopropanes are most often the final products. However, there are a few cases where these intermediates behave surprisingly differently. This Minireview highlights the parallels in reactivity between arynes and D–A cyclopropanes thereby shedding light on the neglected similarities of these two reactive species. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > Arynes和供体 - 受体（D-A）环丙烷是两类紧张系统，其具有许多在有机合成中的应用。过去二十年目睹了这些物种的化学物质的文艺复兴，主要是因为它们的发电或激活的温和和鲁棒方法。通常，植物容易极化系统导致1,2类，而D-A环丙烷作为偏振系统导致1,3-双功能化，从而示出了引人注目的相似性。转化为1,2-和1,3-偶极物提供循环结构。与arynes一起出现的四元环作为中间体可能会进一步反应，而从d-a环丙烷获得的类似五元环是最终的最终产品。然而，有一些案例这些中间体表现出令人惊讶的不同。该Minireview突出了果实和D-A环丙烷之间的反应性方面的平行，从而脱落在忽略这两个反应性物种的忽略相似之处。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-19011/'>《Angewandte Chemie》</a> <b style="margin: 0 2px;">|</b><span>2020年第9期</span><b style="margin: 0 2px;">|</b><span>共14页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Werz Daniel B.&option=202" target="_blank" rel="nofollow">Werz Daniel B.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Biju Akkattu T.&option=202" target="_blank" rel="nofollow">Biju Akkattu T.;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Institut für Organische ChemieTechnische Universit?t BraunschweigHagenring 30 38106 Braunschweig Germany;</p> <p>Department of Organic ChemistryIndian Institute of ScienceBangalore 560012 India;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1188.html" title="应用化学">应用化学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=annulations&option=203" rel="nofollow">annulations;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=arynes&option=203" rel="nofollow">arynes;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=cyclopropanes&option=203" rel="nofollow">cyclopropanes;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=donor–acceptor systems&option=203" rel="nofollow">donor–acceptor systems;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=insertions&option=203" rel="nofollow">insertions;</a> </p> <div class="translation"> 机译：arnulation;arynes;环丙烷;捐赠者 - 受体系统;插入;
