摘要

Abstract > An example of a [3+2] cycloaddition reaction between azaoxyallyl cations generated in?situ and a variety of vinyl benzoxazinanones has been developed. This reaction provides an attractive method for the synthesis of spirooxazoline‐4‐ones based on dihydrobenzoxazines, which were obtained in good yield (up to 98% yield) with high diastereoselectivity (up to 20?:?1). The synthesized spiro‐bis‐ N , O ‐heterocycles can be used as building blocks toward the synthesis of other useful compounds. </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> > 已经开发了在α原位和各种乙烯基苯并嗪酮的亚沙氧基阳离子之间的[3 + 2]环加入反应的实例。 该反应提供了合成基于二氢苯并嗪的螺氧唑啉-4-苯并异恶嗪的合成方法，其具有良好的产率（高达98％产率），具有高的非对映选择性（高达＆ 20？：1）。 合成的螺丝 - n </ i> 那 o </ i> - 呼吸依念可以用作合成其他有用的化合物的结构块。 </ 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-19765/'>《Asian Journal of Organic Chemistry》</a> <b style="margin: 0 2px;">|</b><span>2019年第11期</span><b style="margin: 0 2px;">|</b><span>共5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=Kim Eunjin&option=202" target="_blank" rel="nofollow">Kim Eunjin;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Mun Dasom&option=202" target="_blank" rel="nofollow">Mun Dasom;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Kim Sung‐Gon&option=202" target="_blank" rel="nofollow">Kim Sung‐Gon;</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>Department of ChemistryKyonggi University154-42 Gwanggyosan-ro Yeongtong-gu Suwon 16227 Republic of Korea;</p> <p>Department of ChemistryKyonggi University154-42 Gwanggyosan-ro Yeongtong-gu Suwon 16227 Republic of Korea;</p> <p>Department of ChemistryKyonggi University154-42 Gwanggyosan-ro Yeongtong-gu Suwon 16227 Republic of Korea;</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/1184.html" title="有机化学">有机化学;</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=spiro compounds&option=203" rel="nofollow">spiro compounds;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=dihydrobenzoxazines&option=203" rel="nofollow">dihydrobenzoxazines;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=tetrahydroisoquinolines&option=203" rel="nofollow">tetrahydroisoquinolines;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=cations&option=203" rel="nofollow">cations;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=benzoxazinanones&option=203" rel="nofollow">benzoxazinanones;</a> </p> <div class="translation"> 机译：螺铜化合物;二氢苯并嗪;四氢异喹啉;阳离子;苯并恶唑酮;
