A multi-component reaction involving arynes, N-heteroaromatic compounds (including pyridine, quinoline, and isoquinoline), and aldehydes or ketones for the synthesis of benzo-annulated 1,3-oxazine derivatives has been described. The whole process is carried out under mild conditions and furnishes the desired products in 35–85% yields. Furthermore, regioselectivity and diastereoselectivity can be observed
已经描述了涉及芳烃,N-杂芳族化合物(包括吡啶,喹啉和异喹啉)以及醛或酮的多组分反应,用于合成苯并环化的1,3-恶嗪衍生物。整个过程在温和的条件下进行,以35-85%的产率提供所需的产品。此外,当在该反应中使用3-OMe芳烃前体时,可以观察到区域选择性和非对映选择性。
