摘要:
A manufacturing method is described for the preparation of optically active 1-aromatic-group-substituted-1-alkanones characterized in that an optically active alkane acid halide is allowed to react with an aromatic compound in the presence of a Lewis acid. The optically active 1-aromatic-group-substituted-1-alkanones are useful intermediates in the preparation of optically active alpha-arylalkanoic acids, which are useful as pharmaceutical, e.g. anti-inflammatory, analgesic and anti-pyretic, agents and as insecticidal agents.
