概要
- 論文の詳細を見る
Treatment of isatoic anhydrides with hydrazine hydrate gave 1,2-bis-(o-aminobenzoyl)-hydrazines (IIa-c). The reaction of IIa, b with ethoxymethylenemalononitrile, ethyl ethoxymethylenecyanoacetate or triethyl orthoformate afforded new 3,3'-bisquinazoline-4,4'-diones (IIIa, b and IVa-d) in good yields. On the other hand, the reaction of IIa-c with polyphosphoric acid furnished 2,5-diaryl-1,3,4-oxadiazole derivatives in high yields.
