bromides to form 5‐alkylimino‐2,5‐dihydrofuran‐3,4‐dicarboxylate in relatively good yields at room temperature under solventless conditions. Hydrolysis of these compounds by HCl (5%) produced substituted furanones. J. Heterocyclic Chem., (2011).
由烷基异氰化物和炔属酯形成的两性离子1:1中间体被烷基溴捕获,以在室温下在无溶剂条件下以相对较高的收率形成5-烷基亚氨基-2,5-二氢呋喃-3,4-二羧酸酯。这些化合物被HCl(5%)水解产生取代的呋喃酮。J.杂环化学。(2011)。
