protocol to access heterocyclic dihydroquinazolinones by a transition-metal-free process, involving the reaction of 2-aminobenzonitriles with aldehydes in the presence of KOtBu. The method is compatible with aromatic ketones providing 2,2-disubstituted dihydroquinazolinones in high yields. This reaction proceeds feasibly at room temperature and features a broad substrate scope and tolerance to a range
我们在此报告了一种通过无过渡金属工艺获得杂环二氢喹唑啉酮的有效合成方案,包括在 KO t Bu存在下 2-氨基苯甲腈与醛的反应。该方法与芳族酮兼容,以高产率提供 2,2-二取代二氢喹唑啉酮。该反应在室温下可行,具有广泛的底物范围和对一系列官能团的耐受性。该机制遵循激进的途径。
