Novel and efficient synthesis of cyanidin 3-O-β-D-glucoside from (+)-catechin via a flav-3-en-3-ol as a key intermediate

A novel and efficient synthesis of cyanidin 3-O-β-D-glucoside (1) was accomplished the first time by a biomimetic oxidation route. From (+)-catechin, 3-OH was glucosylated, and the 4-position of the nucleus was then oxidized and dehydrated to give the 5,7
