AbstractA novel method for the synthesis of 3-(2-substituted ethyl)-2-methylbenzohetero[3,2-a]pyrimidines in high yield (80–85%) was achieved, which involves a dihydrofuranone intermediate, readily obtained from β-ketolactone to 2-aminobenzoheterocycles. The major advantage of the methodology is the high yield and product purity. Graphical Abstract
摘要实现了高产率(80-85%)合成3-(2-取代的乙基)-2-甲基苯并杂[3,2- a ]嘧啶的新方法,该方法涉及一种容易从β-得到的二氢呋喃酮中间体。酮内酯转化为2-氨基苯并杂环。该方法的主要优点是高产率和产物纯度。 图形概要
