New arylahdehyde oxime ethers functionalised with N3-3,4-dihydropyrimidinone and 2,5-quinazolinedione groups were synthesised in moderate to good yields by the reaction of the corresponding 3,4-dihydropyrimidinones and quinazolinediones with paraformaldehyde and arylaldehyde oximes via a one-pot two-step strategy in the presence of chlorotrimethylsilane. The advantages of this method are the simple
通过一锅法将相应的 3,4-二氢嘧啶酮和喹唑啉二酮与多聚甲醛和芳醛肟反应,以中等至良好的收率合成了用 N3-3,4-二氢嘧啶酮和 2,5-喹唑啉二酮基团官能化的新型芳醛肟醚在三甲基氯硅烷存在下的两步策略。该方法的优点是操作简单,产物区域选择性高,反应条件温和。
