Abstract: The first synthetic strategy for nonsymmetrical 3,3″-biflavones is described. To this end, a novel visible-light iridium-catalyzed radical C-3 alkylation of flavones with o-methoxy phenacyl bromides was developed. Selective demethylation of the alkylated flavones and acylation… read more here.
