- Faculty of Science, Mansoura University, Mansoura, Egypt Manuscript received 4 August 1980, accepted 23 February 1981 When 6-acetoacetyl-5-methoxy-(1b) and 5-acetoacetyl-6-methoxy-2,3-diphenylbenzofuran (2b) were treated with cyanoacetamide, the corresponding nicotinonitriles were obtained. Compounds 1b and 2b reacted with ethyl cyanoacetate in presence of ammonium acetate to give the benzofuranyl-pyrone derivatives while when the reactions were carried out in presence of diethylamine led to the formation of furochromones. Hydrazine hydrate, phenylhydrazine and semicarbazide hydrochloride reacted with 1b and 2b with the formation of the corresponding pyrazoles. The corresponding isoxazole derivatives were formed by the reaction of lb and 2b with hydroxylamine hydrochloride.
