synthesis of iminocoumarin aryl methyl ethers has been developed from ynal, phenol, and sulfonyl azide at ambient conditions via a cascade [3 + 2]-cycloaddition, 1,3-pseudopericyclic ketenimine rearrangement, 1,4-conjugate addition, and aldol-type condensation. This protocol provides a potential route for the construction of a library of iminocoumarin aryl methyl ethers in good yields.
在环境条件下,通过级联[3 + 2]-环加成,1,3-伪杂环酮亚胺重排,1可以从铜,苯和磺酰叠氮化物开发铜(I)催化的一锅合成亚氨基香豆素芳基甲基醚。,4-共轭加成,和醇醛型缩合。该方案为以高收率构建亚氨基香豆素芳基甲基醚的文库提供了可能的途径。
