A convenient, six-step synthesis of the so far unknown trans-resveratrol-d 4, (E)-3′,4,5′-trihydroxy-2,3,5,6-tetradeuterostilbene, starting from commercially available phenol-d 6, with an overall yield of 25%, is described. The final labeled resveratrol was fully characterized by MS, IR, and ¹H and ¹³C NMR spectroscopy. The isotopic distribution of the final product, determined by high resolution mass spectrometry, was as follows: d 4, 96%; d 3, 4%.
本文介绍了一种简便的六步合成方法,从市售苯酚-d 6 开始,合成迄今未知的反式白藜芦醇-d 4,即(E)-3′,4,5′-三羟基-2,3,5,6-四氘代二苯乙烯,总收率为 25%。通过质谱、红外光谱、¹H 和 ¹³C NMR 光谱对最终标记的白藜芦醇进行了全面表征。经高分辨率质谱测定,最终产品的同位素分布如下:D 4,96%;D 3,4%。
