A facile method for the synthesis of N-aryl-substituted azacycles from arylamines and cyclic ethers has been developed. In this study, arylamines were treated with cyclic ethers in the presence of POCl3 and DBU to provide five- and six-membered azacycles. Using this method, various azacycloalkanes, isoindolines, and tetrahydroisoquinolines were prepared in high yields. This synthetic method offers
已经开发了一种从芳基胺和环醚合成N-芳基取代的氮杂环化合物的简便方法。在这项研究中,芳基胺在POCl 3和DBU的存在下用环醚处理,以提供五元和六元氮杂环。使用这种方法,可以高收率制备各种氮杂环烷烃,异吲哚啉和四氢异喹啉。这种合成方法为由环醚生产氮杂环化合物提供了一种有效的方法。
