摘要:
A novel and conveient one-pot synthesis of 3-aroyl-7-hydroxy-6-nitroflavones from 2',4'-dihydroxy-5'-nitroacetophenone and (substituted)benzoyl chlorides in refluxing dry acetone in the presence of anhydrous potassium carbonate was developed. The structures of the prepared compounds were characterized by IR, H-1 NMR, and MS spectroscopy.
