p-Formycinnamic acid, which usually crystallizes in either the β-form or γ-form of packing, was converted into its diethyl acetal. The introduction of such bulky groups onto a benzene ring successfully provided us with the α-form of packing, from which the desired photodimer, 2,4-di(p-formyl)-α-truxillic acid (c-2, t-4-bis(p-formylphenyl)-r-1,t-3-cyclobutanedicarboxylic acid) was obtained with a yield of 85–90%.
对甲氧基肉桂酸通常以β-形式或γ-形式的堆积结晶,我们将其转化为二乙基缩醛。我们成功地在苯环上引入了这种大分子基团,从而获得了α形式的填料,并从中得到了所需的光二聚体--2,4-二(对甲酰基)-α-曲昔酸(c-2, t-4-双(对甲酰基苯基)-r-1,t-3-环丁烷二羧酸),收率为 85-90%。
