Abstract

Ultrasound-assisted synthesis of pyrimido‌quinolindione derivatives via a multicomponent reaction and subsequent formylation with Vilsmeier-Haack reagent were performed. Compounds were prepared by a one-pot method from aminopyrimidinones, dimedone and aromatic aldehydes through a Mannich-type reaction sequence, and then functionalized under ultrasound irradiation and Vilsmeier-Haack conditions to give β-chlorovinylaldehyde products. Ultrasonically assisted reactions, experimental simplicity, good yields without using metallic catalysts and the control of hazardous material release are features of this simple procedure.

摘要

通过多组分反应超声辅助合成嘧啶并喹啉二酮衍生物,随后用Vilsmeier-Haack试剂进行甲酰化反应。化合物由氨基嘧啶酮、二氢嘧啶酮和芳香醛通过一锅法经曼尼希型反应序列制备,然后在超声辐射和Vilsmeier-Haack条件下进行官能化反应,得到β-氯代乙烯基醛产物。超声辅助反应、实验简单、无需使用金属催化剂即可获得良好产率以及控制有害物质释放是此简单方法的特点。
