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.

Method for the production of diarylcycloalkyl derivatives

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.

Xanthine and phenazone-acesulfame-H complexes having improved taste, process for their preparation and their use

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.

Antimicrobially active acesulfame complexes, process for their preparation and their use

Acesulfame-metal complexes, formed from a trace element, preferably Fe, Zn, Cu, Mn, Co and 2 molecules of acesulfamic acid by precipitation reaction with the use of suitable salts, are distinguished by a pleasantly sweet taste and are therefore suitable as sweeteners, food supplements and for enrichment of food, medicaments and feeds with trace elements.
