PYRROLES. THIOPHENES, AND FURANS FROM 1,4-DICARBONYL COMPOUNDS... [Pg.761]

The ring synthesis of five-membered heterocycles has been extensively investigated, and many and subtle methods have been devised. Each of these three heterocyclic systems can be prepared from 1,4-dicarbonyl-compounds, for furans by acid-catalysed cyclising dehydration, and for pyrroles and thiophenes by interaction with ammonia or a primary amine, or a source of sulfur, respectively. [Pg.292]
