Synthesis of Furan Derivatives. LIX. Synthesis of 5-Substituted-2-(2-furyl)-1, 3, 4-oxadiazoles from 1-Furoyl-2-arylidenehydrazine with Lead Tetraacetate

抄録

It was found out that N-(2-furoyl)-N'-aryl aldehyde hydrazones (Schiff's base) were even more available as starting material for the formation of the corresponding 2-(2-furyl)-5-aryl-1, 3, 4-oxadiazole rings by the oxidative cyclization of lead tetraacetate.
