Abstract

A general procedure was developed for the annelation of a butenolide to an aromatic ketone that highlighted a manganese (III) oxidation of aromatic ketones. The oxidation of aromatic ketones with manganese (III) acetate in the presence of 2-bromoacetic acid or the Mn (II) salt of this carboxylic acid provided a regioselectively convenient synthesis of 2-(2- bromoacetoxy) ketones. An Arbuzov or Wittig reaction of 2-(2-bromoacetoxy) ketones ...
