The present invention relates to a series of substituted dihydro and tetrahydro oxazolopyrimidinones, specifically, to a series of 2-substituted-2,3-dihydro-oxazolo[3,2-a]pyrimidin-7-ones and 2-substituted-2,3,5,6-tetra-hydro-oxazolo[3,2-a]pyrimidin-7-ones of formula (I): Wherein p, n, X, Y, R1, R2, R3, R4, R5, R6, R7 and R8 are as defined herein. This invention also relates to methods of making these compounds including novel intermediates. The compounds of this invention are modulators of metabotropic glutamate receptors (mGluR), particularly, mGluR2 receptor. Therefore, the compounds of this invention are useful as pharmaceutical agents, especially in the treatment and/or prevention of a variety of central nervous system disorders (CNS), including but not limited to acute and chronic neurodegenerative conditions, psychoses, convulsions, anxiety, depression, migraine, pain, sleep disorders and emesis.
La présente invention concerne une série de dihydro et tétrahydro oxazolopyrimidinones substituées, spécifiquement, une série de 2,3-dihydro-oxazolo[3,2-a]pyrimidin-7-ones 2-substituées et de 2,3,5,6-tétra-hydro-oxazolo[3,2-a]pyrimidin-7-ones 2-substituées de formule (I) : dans laquelle p, n, X, Y, R1, R2, R3, R4, R5, R6, R7 et R8 sont tels que définis dans le présent document. L'invention concerne également des procédés de fabrication de ces composés y compris de nouveaux intermédiaires. Les composés de cette invention sont des modulateurs des récepteurs métabotropiques du glutamate (mGluR), particulièrement, du récepteur mGluR2.
