Abstract
AbstractSuzuki–Miyaura reactions of the bis(triflate) of 5,7‐ and 7,8‐dihydroxyflavone proceed with very good site selectivity in favor of position 7 and allow the synthesis of various arylated flavones. The reaction of 5,7‐dihydroxyflavone with one equivalent of triflic anhydride also proceeds with very good site selectivity in favor of position 7. The subsequent Suzuki–Miyaura reaction of the product allows the synthesis of 7‐aryl‐5‐hydroxyflavones. The regioselectivity is discussed based on DFT calculations.
