1-(2,4-二羟苯基)-2-(3,4-二甲氧苯基)乙酮

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In a similar manner to Example 2.1 above, 1-(2,4-dihydroxyphenyl)-2-(3,4-dimethoxy-phenyl)-ethanone dissolved in DMF had added boron trifluoride diethyl etherate followed by methanesulfonyl chloride in DMF. Addition of water to the reaction mixture afforded 3-(3,4-dimethoxyphenyl)-7-hydroxychromen-4-one.
