Abstract

3-acetyltropolone was substituted by bromine at ice-water temperature in the presence of acetic acid to give 3-acetyl-5,7-dibromotroplone(1).Then compound(1) was reacted with aryl-hydrazine,hydrazine hydrate,hydroxylamine and NaN3,respectively to get compounds 2a-d,3,4 and 5.The purities of the compounds were within 91.7-100%.And the structures of the compounds were confirmed by IR,HNMR,MS data.
