Abstract

Abstract From α-nitroolefines 1 and β-diketones 2 3-acetyl4, 5-dihydro-5-(methy1eneamino) furans 5 are prepared. Furans 5 react in acid medium to yield 1-unsubstituted 3-acylpyrroles 6, catalytic hydrogenation yields 1-substituted 3-acylpyrroles 9. The 1 H-nmr and 13 C-nmr investigations prove the constitutions. Abstract Aus α-Nitroolefinen 1 und β-Diketonen 2 werden 3-Acyl-4, 5-dihydro-5-(methylenamino) furane 5 dargestellt. Die Furane 5 ...
