英文摘要	A formal [4 + 1] annulation of readily available alpha-arylhydrazonoketones and trimethylsulfoxonium iodide in the presence of cesium carbonate is described involving a sequential corey-chaykovsky reaction and intramolecular nudeophilic cyclization process. substituted pyrazoles were obtained exclusively from the reactions of alpha-arylhydrazono-beta-oxo-amides and trimethylsulfoxonium iodide in moderate to good yields, whereas the reactions of alpha-arylhydrazono-beta-oxo-ketone/alpha-arylhydrazono-, beta-oxo-ester afforded the corresponding dihydropyrazoles in good yields.
