| Research Abstract |
Anthocyanins are widely found in plants and play important roles in insect pollination, anti-oxidation, and protection from harmful light. Recently, these pigments have also shown potential as functional food colorants and can be useful dyes for organic solar-sensitized cells. To establish a new and efficient synthetic method of anthocyanins we tried to transform flavonol derivatives by metal reduction. We clarified that metal reduction of flavonol compound first gave corresponding flavenol compound, then this was oxidized by air to give anthocyanin. This reaction is mild and can be applicable for the synthesis of the acylated anthocyanin.
