The present invention relates to novel compounds, in particular novel pyridinone derivat ives according to Formula (I) X R1 N Y (I) R2 R3 wherein all radicals are defined in the application. The compounds according to the invention are positive allosteric modulators of metabotropic receptors - subt ype 2 ('mGluR2') which are useful for the treatment or prevention of neurological and psychiatric disorders associated with glutamate dysfunction and diseases in which the mGluR2 subtype of metabotropic receptors is involved. In particular, such diseases are central nervous system disorders selected from the group of anxiety, schizophrenia, migraine, depression, and epilepsy. The invention is also directed to pharmaceutical compositions and processes to prepare such compounds and compositions, as well as to the use of such compounds for the prevention and treatment of such diseases in which mGluR2 is involved.
本发明涉及新化合物,特别是根据式(I)X R1 N Y(I)R2 R3定义的新吡啶酮衍生物。根据本发明的化合物是代谢型受体-亚型2('mGluR2')的阳性变构调节剂,对于治疗或预防与谷氨酸功能障碍相关的神经和精神障碍以及涉及代谢型受体的mGluR2亚型的疾病具有用处。特别是,这些疾病是从焦虑、精神分裂症、偏头痛、抑郁症和癫痫等中枢神经系统障碍组中选择的。该发明还涉及制备此类化合物和组合物的药物组合物和过程,以及利用这类化合物预防和治疗涉及mGluR2的这类疾病。

availability and low toxicity of the required reagents, mild reaction conditions, and functional group compatibility. Nevertheless, few conditions can be used to cross-couple alkyl boronic acids or esters with aryl halides, especially 2-pyridyl halides. Herein, we describe two novel Suzuki–Miyaura protocols that enable selective conversion of polychlorinated aromatics, with a focus on reactions to convert

catalytic nickel complexes in sp2-sp3 cross-electrophile coupling reactions has been developed. The electrochemical reduction provides reliable nickel catalyst activation and turnover and offers a tunable parameter for reaction optimization, in contrast to more standard activated metal powder reductants. The electrochemical reactions give yields (i.e., 51–86%) and selectivities as high or superior to
