In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 69778-83-2, name is 4-Methoxy-1H-pyrrol-2(5H)-one, introducing its new discovery. Application In Synthesis of 4-Methoxy-1H-pyrrol-2(5H)-one
Synthetic routes to pyrrolizine-1,5-dione derivatives by flash vacuum pyrolysis of amidomethylene derivatives of Meldrum’s acid
Methoxymethylene Meldrum’s acid 1 reacts with 5- and 6-membered lactams in refluxing acetonitrile to give the N-substituted products 9-15. If the reactions are continued for extended times, the Meldrum’s acid derivatives decompose to provide enamidoesters e.g.22-24. Flash vacuum pyrolysis of the 5-membered ring products 9-13 provides reasonable yields of the fused pyrrolones 31-35. The constitution of the products is supported by X-ray crystal structures of 10, 12, 19, 32 and 34. The Royal Society of Chemistry 2009.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 69778-83-2, and how the biochemistry of the body works.Application In Synthesis of 4-Methoxy-1H-pyrrol-2(5H)-one
