Abstract
Aryl-and benzoyl-hydrazones of 2,4-O benzylidene D-erythrose were prepared and acetylated. D-glycero-Tetrulose phenyl-and p-substitute-phenyl-osazones were acylated with acetyl chloride and benzoyl chloride to give the N-acyl-di-O-acyl derivatives, which, on boiling with acetic anhydride, afforded the 1-aryl-3-formylpyrazole N-acetylarylhydrazones. The bis(hydrazones) of 2,3-dioxo-y-butyrolactone are partially hydrolyzed with copper(II) chloride to give the 2-hydrazono-3-oxo-y-butyrolactones, which, on treatment with alkali, rearrange to give the 1-aryl-3-hydroxymethylpyrazoline-4,5-dione 4-arylhydrazones. © 1976.
