Abstract
The total synthesis of apigeninidin (1 ),luteolinidin (2 ) and 5,7-dihydroxyflavylium(5 ) chlorides is performed through a onestep reaction from an acetylated derivative
of a commercial reagent.Condensation reaction between 2,4,6-triacetoxybenzaldehyde
and anacetophenone derivative in anhyd methanolic hydrogen chloride providesthe 3-deoxyanthocyanidins
in high yields.
Key words
total synthesis - natural products - heterocycles - polycycles - phenols
