  • Method for the production of diarylcycloalkyl derivatives
    Patent number: 7803950
    Abstract: The invention relates generally to a process for preparing diarylcycloalkyl derivatives of the formula (I). wherein the respective R-group substituents are defined herein. These compounds of formula (I) are activators for peroxisome proliferator-activated receptors (PPAR activators) which are useful in the therapeutic treatment of a number of diseases and disorders of the central nervous system such as multiple sclerosis, Parkinson's Disease, psychiatric disorders and the like. The present invention is a novel process for preparing PPAR activators of the formula (I) which do not have the disadvantages of the processes known in the prior art. In particular, a process is provided with which the PPAR activators of formula (I) can be prepared in a suitable enantiomeric excess, i.e. high enantioselectivity, without the need for subsequent chiral chromatography.

  • Process for the preparation of substituted 2-(phenoxymethyl)benzoic acids
    Patent number: 7582794
    Abstract: The invention relates to a process for the preparation of a compound of the general formula (I) in which a) a compound (II) is reacted in the presence of a base B1 with a compound (III) and b) the compound (IV) formed as intermediate in step a) is reacted in the presence of a base B2 with a compound (V) to give the compound of the general formula (I)

  • NOVEL INTERMEDIATE COMPOUNDS USEFUL IN THE PRODUCTION OF DIARYLCYCLOALKYL DERIVATIVES
    Publication number: 20080051583
    Abstract: The invention relates generally to intermediate compounds derived during the process for preparing diarylcycloalkyl derivatives which are activators for peroxisome proliferator-activated receptors (PPAR activators) and are therefore useful in the therapeutic treatment of a number of diseases and disorders of the central nervous system such as multiple sclerosis, Parkinson's Disease, psychiatric disorders and the like. The intermediate compounds of the present invention are defined structurally by the formulae (Ia): and formula (II): wherein the respective substituent groups are defined herein.
