First observed oxidative phenol coupling to the β-position of a chalcone
Abstract
2′,4-Dihydroxy-4′,6′-dimethoxy-trans-chalcone couples at the β-position with 3,5-dimethoxyphenol under oxidative conditions to form stereoisomeric 2-[α-(4-hydroxy-2,6-dimethoxyphenyl)-4-hydroxybenzyl]-4,6-dimethoxybenzo [b]furan-3(2H)-ones.
