Auwers synthesisThe Auwers synthesis is a series of organic reactions forming a flavonol from a coumarone. This reaction was first reported by Karl von Auwers in 1908.[1][2][3][4] Additional recommended knowledgeThe first step in this procedure is an acid catalyzed aldol condensation between benzaldehyde and a 3-oxypentanone to a o-hydroxychalcone. Bromination of the alkene group gives a dibromo-adduct which rearranges to the flavonol by reaction with potassium hydroxide. ReferencesSee also
