A simple, convenient and high-yielding one-pot method for the synthesis of 2-heterocycle-substituted imidazoles from the corresponding nitriles has been developed. The procedure is easily scaleable and the workup does not involve chromatography. This synthesis is also applicable to the preparation of imidazoles with electron-poor aryl substituents.
Starting from commercially available (hetero)aromatic nitriles and (1R,2R)-cyclohexane-1,2-diamine, nine NH-imidazolines (hexahydro-1H-benzo[d]imidazoles) were synthesized in good yields. The molecular structures of three imidazolines were confirmed by X-ray analysis. N-Benzylation afforded some of the desired N-benzylimidazolines, but was incompatible with imidazolines that possessed strong electron-accepting
从市售的(杂)芳族腈和(1 R,2 R)-环己烷-1,2-二胺开始,以高收率合成了九种NH-咪唑啉(六氢-1 H-苯并[ d ]咪唑)。通过X射线分析证实了三种咪唑啉的分子结构。N-苄基化提供了一些所需的N-苄基咪唑啉,但与在C2具有强电子接受杂芳族基团的咪唑啉不相容。在后一种情况下,产物在柱色谱法中分解形成N,N'-二取代的环己烷-1,2-二胺。 杂环-咪唑啉-手性池- N的-苄基-稳定性
