Abstract

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%.
