3,4-二甲氧基苯甲醛与环糊精形成1:1的包合物。它与3-乙酰基-2,5-二甲基噻吩反应生成查尔酮染料2E)-3-(3,4-二甲氧基苯基)-1-(2,5-二甲基噻吩-3-基)丙-2-烯-1-酮。 3,4-二甲氧基苯甲醛用于制备4-氯甲基-2-(二甲氧基苯基)-1,3-二氧戊环。用于合成具有抗HIV活性的(+)-紫草酸。 3,4-dimethoxybenzaldehyde and cyclodextrin form a 1:1 inclusion compound. It reacts with 3-acetyl-2,5-dimethylthiophene to form chalcone dye 2e-3 - (3,4-dimethoxyphenyl) - 1 - (2,5-dimethylthiophene-3-yl) propyl-2-ene-1-one. 3,4-dimethoxybenzaldehyde is used to prepare 4-chloromethyl-2 - (dimethoxyphenyl) - 1,3-dioxygentyl. It is used to synthesize the (+ - violet acid) with anti HIV activity.
