Highly Efficient One-Pot Synthesis of 2-Substituted Quinazolines and 4<i>H</i>-Benzo[<i>d</i>][1,3]oxazines<i>via</i>Cross Dehydrogenative Coupling using Sodium Hypochlorite
describes a catalyst-free synthesis of 2-substitutedquinazolines and 4H-benzo[d][1,3]oxazines using commericially available sodiumhypochlorite as oxidant. Operational simplicity, mild reaction conditions and the ability to construct structurally diverse 2-quinazolines and 2-substituted4H-benzo[d][1,3]oxazines by this method render it to be a practical alternative for the synthesis of these heterocycles
该通报描述了使用市售的次氯酸钠作为氧化剂的无催化剂合成2-取代的喹唑啉和4 H-苯并[ d ] [1,3]恶嗪。操作简便,反应条件温和以及通过该方法构造结构上不同的2-喹唑啉和2-取代的4 H-苯并[ d ] [1,3]恶嗪的能力使其成为合成这些杂环的实用选择。
