Abstract
Phloroglucinol-type 3-deoxyanthocyanidins were synthesized through the interaction between phloroglucinol derivatives and arylethynylketones in acetic acid in the presence of aqueous hexafluorophosphoric acid. This methodology was applied to achieve the synthesis of natural apigeninidin, luteolinidin and tricetanidin with high yields.
