The title compound, 3, 6-dihydroxy-2-[2-(4-hydroxy-phenyl)-vinyl]- benzene-1,3-dicarbaldehyde was synthesized by Vilslmeier reaction from resveratrol (trans-3,4′,5-trihydroxystilbene). Its structure was determined by X-ray single crystal diffraction. The crystal belongs to monoclinic, space group P21/n with crystallographic parameters: a = 7.2950(15) Å, b = 14.781(3) Å, c = 12.202(2) Å, β = 96.57(3)°, μ = 0.108 mm−1, V = 1307.1(5) Å, Z = 4, Dx = 1.445 g/cm3, F(000) = 592, T = 293(2) K, 2.17°≤ θ ≤ 26.00°. The X-ray results demonstrated that the Vilslmeier reaction of resveratrol with DMF, POCl3 and CH3CN yielded 4,6-dhydroxy-2-[2-(4-hydroxy-phenyl)-vinyl]-benzene-1,3-dicarbaldehyde. In this article, a resveratrol derivative was prepared and structurally characterized by single crystal X-ray diffraction.
通过Vilslmeier反应从白藜芦醇(反式-3,4',5-三羟基二苯乙烯)。通过X射线单晶衍射测定了其结构。该晶体属于单斜晶系,P21/n空间群,晶体学参数:a = 7.2950(15) Å, b = 14.781(3) Å, c = 12.202(2) Å, β = 96.57(3)°, μ = 0.108 mm−1,V=1307.1(5)Å,Z=4,Dx=1.445g/cm3,F(000)=592,T=293(2)K,2.17°≤θ≤26.00°。 X射线结果表明,白藜芦醇与DMF、POCl3和CH3CN发生Vilslmeier反应,生成4,6-d羟基-2-[2-(4-羟基苯基)-乙烯基]-苯-1,3-二甲醛。本文制备了一种白藜芦醇衍生物,并通过单晶 X 射线衍射进行了结构表征。
