本文以3-乙醛基-4-羟基-6-溴喹啉为原料, 经与芳香醛缩合得查尔酮类化合物, 而后环合, 氧化生成2-芳基-4-氧-4H吡喃酮[3,3,-c]-9-溴喹啉类化合物。本文合成了七个查尔酮类化合物和七个氮杂黄酮类化合物。

Title compounds I (R = H, Cl; R1 = H, Cl, OH, MeO; R1 = H, OH, NO2) were synthesized from chalcones II with I2-DMSO-H2SO4. The chalcones were first heated at 100~120?for about 10 min. in DMSO in the presence of H2SO4 and then the reaction mixture was further heated in the presence of a small amount of iodine to give 50~85% yields of compounds I.

Key words: FLAVONOID, BENZALDEHYDE P, BROMINE COMPOUNDS, CHALCONE P, ACETALDEHYDE P, BROMIDE, PYRANONE P, BENZENE P, QUINOLINE P, QUINOLINE P
