An efficient and convenient approach has been developed for the synthesis of naphtho[1,2- f ][1,4]oxazepine structures based on the consecutive Betti/Bargellini multicomponent reactions. Aminobenzylnaphthols were prepared from 2-naphthol, aromatic aldehydes, and 2-aminopyridine via the Betti reaction, and then, naphtho[1,2- f ][1,4]oxazepine derivatives were synthesized using the Betti reaction products
基于连续 Betti/Bargellini 多组分反应,已开发出一种高效便捷的合成萘并[1,2-f][1,4]氧氮杂卓结构的方法。由 2-萘酚、芳香醛和 2-氨基吡啶通过 Betti 反应制备氨基苄基萘酚,然后使用 Betti 反应产物、氯仿和脂肪族化合物合成萘并[1,2-f][1,4]氧氮杂卓衍生物。在氢氧化钠存在下通过 Bargellini 多组分反应生成酮。这项工作的一个重要方面是从廉价且易于获得的起始材料中以中等产量构建具有潜在药物价值的新型奥西平基支架。图形摘要
