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
