摘要：

(E)-2-(1-(2-Hydroxy-4-methoxyphenyl)ethylideneamino)-3-(4-hydroxyphenyl)methyl propionate (C22H27O6N, Mr = 401.45) has been synthesized by a condensation reaction of paeonol with tyrosin methyl ester hydrochloride, and its structure was determined by IR, NMR, HR MS and X-ray single-crystal diffraction. The crystal belongs to the monoclinic system, space group P21/c, with a = 11.91291(15), b = 9.49947(12), c = 19.8727(3) , β = 106.1104(15)°, V = 2160.60(5)3, Z = 4, Dc = 1.234 g/cm3, μ = 0.739 mm-1, F(000) = 856, R = 0.0466 and wR = 0.1461 for 3859 observed reflections with (Ⅰ> 2σ(Ⅰ)). In the crystal structure, the title compound is constructed by a centrosymmetric dimmer unit composed of a pair of π-π stacking enantiomers, and such units are linked by intermolecular O(5)-H(5)…O(1) and intramolecular N(1)-H(1)…O(1) hydrogen bonds.
