Abstract
Racemic 4-[13C]catechin 14 has been synthesized in ten steps starting from potassium [13C]cyanide. The intermediate chalcone 9 was formed by acylation of the benzylated phloroglucinol 7 with the caffeic acid synthon 6, using the trifluoroacetic mixed anhydride. The flavonoid skeleton was then obtained by previously described reactions such as the reduction of chalcone 9 and dihydroxylation of flavene 11. Such [13C]-labelled polyphenols should prove to be useful tools for human biological investigations.
