variety of 2-methylpyrimidin-4(3 H)-ones promoted by chlorotrimethylsilane was investigated. A simple and flexible general procedure for the synthesis of a series of fused pyrido[1,2- A]pyrimidin-4-ones is proposed. A set of functionally and structurally diverse pyrido[1,2- A]pyrimidin-4-ones were obtained in high yields.
研究了三甲基氯硅烷促进的3-甲酰色酮与多种2-甲基嘧啶-4(3 H)-酮的环化反应。提出了一种用于合成一系列稠合吡啶并[1,2-A]嘧啶-4-酮的简单灵活的通用程序。以高产率获得了一组功能和结构多样的吡啶并[1,2-A]嘧啶-4-酮。
