A New and Convenient Synthesis of 3(2H)-Pyridazinones by Reacting Carbanion of Ethyl Trimethylsilylacetate with Phenylhydrazones
摘要:
A one-pot synthesis of 5,6-disubstituted-2-phenyl-3(2H)-pyridazinones 4 is achieved on treatment of carbanion of ethyl trimethylsilylacetate with phenylhydrazones of 1,2-dicarbonyl compounds 1.
