| Abstract: | Using two kinds of 2-aminobenzophenones with different substituents as raw materials,chlorobenzene as solvent,BF3-Et2O as dehydrating agent,asymmetric dibenzob,f]1,5]diazocines were prepared by intermolecular cyclizative condensation at one step.The synthetic technology was optimized by using high performance liquid chromatography(HPLC)to monitor the reaction process.The best reaction conditions were that the equal moles of two different 2-aminobenzophenones and BF3-Et2O were reacted in refluxed chlorobenzene for 12 h.Compounds 4 a^4 c are new compounds,and their structures were characterized by 1H NMR,13C NMR and MS(ESI),respectively. |
