Abstract

A MnVII-mediated regio- and diastereoselective acyloxyarylation of chalcones is unveiled. Heating a solution of a chalcone and an arylboronic acid in an aliphatic carboxylic acid at 80 °C for 1 h afforded the corresponding 1-acyloxy-3-oxo-1,2,3-triarylpropanes in high yields. The β-acyloxy-α-arylation/elimination sequence can be regarded as an indirect α-arylation of chalcones. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
