| Abstract: | A novel synthesis method of 3,3,6,6-tetramethyl-9-aryl-1,2,3,4,5,6,7,8-octahydroxanthene-1,8-dione was described via condensation of aromatic aldehydes with 5,5-dimethyl-1,3-cyclohexadione using formic acid as catalyst in aqueous without phase transfer reagent,which has many advantages of short reaction time,high yields and environmental friendliness.The structure of final products was identified by ~1HNMR and IR spectra. |
