Abstract

We describe a facile efficient, and preparative approach for monohydroxyflavanone syntheses. Using this protocol, a hydroxyl is regio-selectively introduced at one carbon of a flavanone A-or B-ring per synthesis. The seven possible isomers were each synthesized from the corresponding monomethoxymethoxylated 2′-hydroxychalcones in acidic solution. These monohydroxyflavanones were characterized using a gas chromatography ...
