A new three-component reaction of cyclic β-diketones, formaldehyde and substituted anilines is described. The reaction provides a simple synthetic method for the one-pot preparation of 3-spirosubstituted 1,2,3,4-tetrahydroquinolines containing different substituents at the N-atom. This reaction also gives the opportunity to unite in one molecule the 1,2,3,4-tetrahydroquinoline, cyclic β-dicarbonyl, 2-azaspiro and some other (e.g., benzylic, bicyclic, adamantyl) fragments.
本文介绍了一种由环 δ-二酮、甲醛和取代苯胺组成的新的三组分反应。该反应提供了一种简单的合成方法,可用于一锅制备在 N 原子上含有不同取代基的 3-巯基取代的 1,2,3,4-四氢喹啉。该反应还提供了将 1,2,3,4-四氢喹啉、环δ-二羰基、2-氮杂螺和一些其他(如苄基、双环、金刚烷基)片段结合在一个分子中的机会。
