An efficient deuterium labelling of theaflavin, aiming at radiolabelling of theaflavin, was accomplished for the first time by using 4-deuterium-labelled epi-catechin as the precursor and the resulting D-labelled theaflavin was fully characterized by 1H NMR, 13C NMR, IR spectroscopy and ESI-MS. The synthesis features a novel efficient polyphenol oxidase (PPO) catalyzed benzotropolone formation. PPO was bound onto a selected polymer by a novel efficient method developed in this lab.
