  The present invention relates to ethynyl derivatives of formula I wherein X is N or C-R, wherein R is hydrogen or halogen; G is N or CH; with the proviso that maximum one of G or X can be nitrogen; R1 is phenyl or pyridinyl, which are optionally substituted by halogen; R2 is hydrogen, lower alkyl, hydroxy, lower alkoxy or C(O)O-benzyl; R3,R3', R4, R4, R6, R6' are independently from each other hydrogen or lower alkyl; or R6 and R4 may form together with the carbon atom to which they are attached a C4-6-cycloalkyl ring, if m is 0 and n is 1 or 2; R5 is hydrogen or lower alkyl; n is 0, 1 or 2; m is 0 or 1; with the proviso that n and m are not simultaneously 0; or to a pharmaceutically acceptable acid addition salt, to a racemic mixture, or to its corresponding enantiomer and/or optical isomer and/or stereoisomer thereof. It has now surprisingly been found that the compounds of general formula I are positive allosteric modulators (PAM) of the metabotropic glutamate receptor subtype 5 (mGluR5). They may be used for the treatment of schizophrenia or cognitive disorders.

  本发明涉及公式I的乙炔衍生物，其中X为N或C-R，其中R为氢或卤素；G为N或CH；但G或X最多只能有一个是氮；R1为苯基或吡啶基，可以选择地被卤素取代；R2为氢、低烷基、羟基、低烷氧基或C（O）O-苄基；R3、R3'、R4、R4'、R6、R6'独立地为氢或低烷基；或者当m为0且n为1或2时，R6和R4可以与它们连接的碳原子一起形成一个C4-6环烷基环；R5为氢或低烷基；n为0、1或2；m为0或1；但n和m不能同时为0；或者它的药学上可接受的酸盐、消旋混合物，或其对应的对映体和/或光学异构体和/或立体异构体。现已惊讶地发现，一般公式I的化合物是代谢型谷氨酸受体亚型5（mGluR5）的阳性变构调节剂（PAM）。它们可用于治疗精神分裂症或认知障碍。
