摘要
The 1,4-dicarbonyl and 1,4,7-tricarbonyl compounds 1 cyclize with ammonia or methylamine to yield the pyrroles 2. Dependent on the temp. the 1,4-diketone 1b reacts with hydrazine in ethanole to form the pyridazine 3 or the N-amino-pyrrole 4, respectively. Acetylation of 4 gives the stable amide 5. The N-hydroxy-pyrrole 6 is obtained by condensation of 1b with hydroxylamine.
