Abstract

Abstract: Biologically and pharmaceutically relevant arylated quinones (Quin-Ar) have been synthesized via direct CÀH arylation of a variety of phenols using arylboronic acids. An inexpensive, environmentally friendly iron catalyst, ferric sulphate, Fe2ACHTUNGTRENNUNG (SO4) 3, was employed in this operationally simple and efficient method. Keywords: arylated quinones; arylation; iron catalysis; natural products; phenols
