- 中文摘要: The 2H-1-benzo/naphthopyran-2-one-4-yl (un)substituted phenyl-1,3,4-oxadiazoles has been synthesized by the oxidative cyclization of benzoic acid hydrazides formed in situ by the condensation of the respective 2H-1-benzo/naphthopyran-2-one-4-carboxaldehyde and (un)substituted monobenzoyl hydrazide in moderate yields. Also, spiro[indoline-thiozolidine]-2,4¢-diones has been syhthesized in a similar way from 3-phenyl-spiro[3H-indoline-3,2¢-thiozolidine]-2,4¢-(1H)dione monohydrazide and (un)substituted benzaldehydes.
