[EN] The invention relates to adamantyl-(cyclopropyl)-ketone derivatives as well as their pharmaceutically acceptable salts. The invention further relates to a process for the preparation of such compounds. The compounds of the invention are Group I mGluR modulators and are therefore useful for the control and prevention of acute and/or chronic neurological disorders. [FR] L'invention concerne des dérivés d'adamantyl-(cyclopropyl)-cétone ainsi que leurs sels acceptables sur le plan pharmaceutique. L'invention concerne également un procédé de préparation desdits composés. Les composés de l'invention sont des modulateurs du mGluR du groupe 1 et sont par conséquent utiles pour la lutte et la prévention contre les troubles neurologiques aigus et/ou chroniques.

methyl ketones show significantly decreased reactivities toward the Corey-Chaykovsky methylenation reagent dimethylsulfoxonium methylide (DMSM). The excess of base and temperature increase opens an alternative reaction channel that instead leads to the corresponding cyclopropylketones. Computations suggest that the initial reaction step involves the methylene group transfer from DMSM on the ketone enolate
