The synthesis of [4-14C]-pelargonidin chloride and [4- 14C]-delphinidin chloride via [formyl-14C]-2-(benzoyloxy)- 4,6-dihydroxybenzaldehyde, ω,4-diacetoxyacetophenone and ω,3,4,5-tetraacetoxyacetophenone is described. The first step comprised labelling of the carbonyl group of 2-(benzoyloxy)-4,6-dihydroxybenzaldehyde, verifying that the coupling with ω,4-diacetoxyacetophenone or ω,3,4,5-tetraacetoxyacetophenone under hydrogen chloride atmosphere resulted in the formation of [4-14C] labelled anthocyanidins.
