Reaction of 5-Hydroxyimino-1,3-dioxine-4,6-dione (Isonitroso Meldrum's Acid) with Carbodiimides to Give Parabanic Acids
摘要:
Reaction of 5-hydroxyimino-1,3-dioxine-4,6-dione (isonitroso Meldrum's Acid) with carbodiimides gave cyanoformamide derivatives in quantitative yields, which cyclized to iminoparabanic acids and parabanic acids under basic and acidic conditions, respectively.
