Synthesis of 1, 3-diketone and its reaction with different N-nucleophiles (part II)

Abstract

Treatment of resorcinol with ethyl acetoacetate in presence of conc. sulphuric acid led to formation of 1,3-diketone 3 in several steps, which on reaction with ethylene diamine 4, phenylene diamine 6, hydroxylamine 8, phenyl hydrazine 9 and hydrazine 10 led to formation of 1,4 diazepine 3a, 1, 5-benzodiazepine 3b, isoxazole 3c and pyrazole 3d, 3e derivatives respectively.
