Abstract Acetyl-substituted heterocyclic enamines 4 were synthesized from lactim ethers 2 and acetylacetone through condensation and deacetylation reactions, and they, along with the ester-substituted heterocyclic enamines 6, reacted with diethyl azodicarboxylate to afford C-adducts 7 and 8 in excellent yields.
摘要 由内酰胺醚 2 和乙酰丙酮通过缩合和脱乙酰反应合成了乙酰取代的杂环烯胺 4,它们与酯取代的杂环烯胺 6 一起与偶氮二羧酸二乙酯反应,以优异的收率得到 C-加合物 7 和 8。
