biomimetic aerobic oxidative synthesis of 2-substituted quinazolines and Hantzsch pyridines from the oxidative cyclocondensation of 2-aminobenzylamine and aldehydes and the oxidative aromatization of 1,4-dihydropyridines, respectively. The products were obtained in good to high yields in a phosphate buffer (0.1 M, 12.5 mL, pH 4.5) and acetonitrile (4 vol%) mixture as a solvent. These methods are more
摘要 漆酶/DDQ 作为一种新型的仿生醌基协同催化体系,通过 2-氨基苄胺和醛的氧化环缩合和 1,4-二氢吡啶的氧化芳构化,仿生有氧氧化合成 2-取代喹唑啉和 Hantzsch 吡啶。 , 分别。在磷酸盐缓冲液 (0.1 M, 12.5 mL, pH 4.5) 和乙腈 (4 vol%) 混合物作为溶剂中以良好至高产率获得产物。由于反应条件温和,并且不含任何卤化物和有毒且昂贵的过渡金属,这些方法比其他现有方法更加环保、高效、简单和实用。因此,这些方法可以应用于制药和其他敏感的合成程序。
