butenolide to an aromatic ketone that highlighted a manganese(III) oxidation of an aromatic ketone. The merit of this procedure was illustrated in a synthesis of Chromolaenin (Laevigatin) (1) from 4,7-dimethyl-1-tetralone (2c). Oxidation of tetralone and indanone with manganese(III) acetate in the presence of chloro- or bromopropionic acid or their Mn(II) salts furnished a α-haloesters 3a-d. An Arbuzov
