take part in nucleophilic aromatic substitution (SNAr) reactions is realized in a new three-component, one-pot reaction, giving at least tricyclic annulated quinazolinones, benzoxazinones, and benzothiazinones as a result of the employed nitrogen, oxygen, or sulfur nucleophiles, respectively. Especially in the case of quinazolinones, this convenient strategy enables the access to heterocycles of heightened
在新的三组分一锅法反应中,实现了易于参与的环状亚胺与酰基氯的有效转化,该亚胺能够参与亲核芳香族取代(S N Ar)反应,至少产生三环环化喹唑啉酮,苯并恶嗪酮分别是由于使用了氮,氧或硫亲核试剂而产生的苯并噻嗪酮。特别是在喹唑啉酮的情况下,这种方便的策略使人们能够进入多样性更高的杂环,这为精细杂环骨架的有效衍生化提供了发展。在随后的Heck或Ullmann环化中,可以对所提及的喹唑啉酮进行进一步的环合。
