ABSTRACT:
The present invention relates to novel resolution methods, which are useful in the preparation of enantiomerically enriched intermediates which in their turn are useful in the prepartion of compounds with a pharmacological effect on the insulin resistance syndrome (IRS). It is such a process that the present inventions sets out to define, and more particularly for the preparation of the (S)-enantioner of certain 2-ethoxy-3-(4-hydroxyphenyl)propanoic acids and derivatives thereof.
