摘要

Abstract > Acid‐modified halloysite nanotubes were used for the first time as a stereoselective catalyst for synthesis of oxygen‐containing heterocycles applying of allyl alcohol (?)‐isopulegol condensation with aldehydes to the octahydro‐2 H ‐chromenol (4 R ‐ and 4 S ‐diastereomers) as an example. The catalysts were characterized by XRF, XRD, N <sub>2</sub> ‐adsorption, FTIR with pyridine and MAS NMR methods. A high ratio of 4 R /4 S diastereomers (7.6–14.5) under mild conditions in cyclohexane was considerably exceeding previously reported results. Unprecedented selectivity (79–83?%) to 4 R isomer of thiophenyl‐substituted chromenol exhibiting high analgesic activity was achieved. An increase in stereoselectivity with a decrease in the halloysite drying temperature and catalyst acidity clearly indicates formation of 4 R diastereomer on the weak Br?nsted sites. This work is an example that control of the stereoselectivity of acid‐catalyzed organic reactions can be effectively carried out by varying water content on the aluminosilicate surface. Modified halloysite nanotubes can be considered as extremely promising catalysts for stereoselective synthesis of heterocyclic 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> > 首次使用酸改性的Holloysite纳米管作为合成含氧杂环的立体选择性催化剂，施用烯丙基醇（α） - 与醛醛与八氢盐-2的醛缩合 h </ i> -Chromenol（4.
