An alternative synthetic route to 1,4,5-trisubstituted imidazoles from α-imino ketone, which can be prepared from imidoyl chlorides and aromatic aldehydes via N-heterocycle carbene-catalyzed aroylation was developed. This methodology consists of simple transformations, allowing a rapid access to imidazole derivatives with various aryl substituents at the desired positions.
研究了由α-亚氨基酮制取1,4,5-三取代咪唑的另一种合成路线,该路线可由亚氨基酰氯和芳族醛经N-杂环卡宾催化的芳基化反应制得。该方法包括简单的转化,可以快速获得在所需位置带有各种芳基取代基的咪唑衍生物。
