  • 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.

  • 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.

  • Patent number: 6849623
    Abstract: Complex compounds or adducts of xanthine derivatives, for example propentofylline or pentoxyfylline, or phenazone derivatives, for example phenazone, propylphenazone and aminophenazone, and acesulfame-H, in which the components are present in a molar ratio of 1:1 or 1:2, have a pleasantly sweet taste and are suitable for numerous applications, for example in pharmaceuticals. The compounds can be prepared from the dissolved components by simple reaction.

  • Publication number: 20040173224
    Abstract: Salts formed from nicotine and anion-forming sweeteners, for example acesulfame or acesulfame-K, in a molar ratio of 1:1 or 1:2, in which case the sweetener molecules can be identical or different, are distinguished by a pleasant sweet taste which masks the nicotine taste even after a long residence time in the mouth, and are therefore suitable for producing preparations, in particular chewing gum, chewing tablets or compressed compositions, which can be used for oral administration of nicotine, for example in withdrawal from smoking.

  • Patent number: 6759544
    Abstract: Complex compounds containing acesulfame have good antimicrobial action, in particular antibacterial action, and are distinguished by the fact that they are complex compounds of metallic elements such as zinc, copper, silver, or nonmetallic quaternary ammonium cations, such as the cetylpyridinium cation, with acesulfame. The invention also relates to a process for preparing the compounds and their use in the oral hygiene sector.
