The present invention is directed to pyrimidine carboxamide compounds of formula I which are useful as therapeutic agents for the treatment of central nervous system disorders associated with phosphodiesterase 2 (PDE2). The present invention also relates to the use of such compounds for treating neurological and psychiatric disorders, such as schizophrenia, psychosis, Parkinson's disease, Parkinson's disease dementia (PDD), or Huntington's disease, and those associated with striatal hypofunction or basal ganglia dysfunction.

the selection of 2-bisaryl 3-methyl quinolones as a series for further biological evaluation. The lead compound within this series 7-chloro-3-methyl-2-(4-(4-(trifluoromethoxy)benzyl)phenyl)quinolin-4(1H)-one (CK-2-68) has antimalarialactivity against the 3D7 strain of P. falciparum of 36 nM, is selective for PfNDH2 over other respiratory enzymes (inhibitory IC50 against PfNDH2 of 16 nM), and demonstrates

Primary benzylic boronate esters are useful intermediates in organic synthesis, but these reagents cannot be prepared by hydroboration. The benzylic C-H borylation of methylarenes would be a method to form these products, but such reactions without neat methylarene or a directing group are unknown. We report an approach to divert the borylation of methylarenes from aromatic positions to benzylic positions
主要的苄基硼酸酯是有机合成中有用的中间体,但这些试剂不能通过硼氢化反应制备。甲基芳烃的苄基 CH 硼酸化将是形成这些产物的一种方法,但这种没有纯甲基芳烃或导向基团的反应是未知的。我们报告了一种以甲硅烷基硼烷为试剂和含有缺电子菲咯啉作为配体的新型铱催化剂将甲基芳烃的硼酸化从芳族位置转移到苄位位置的方法。该系统相对于相应的芳基硼酸酯选择性地形成苄基硼酸酯。由菲咯啉连接的 Ir 二硼基单甲硅烷基复合物被分离并确定为催化剂的静止状态。机理研究表明,这种复合物在动力学上有能力成为催化过程中的中间体。各种 Ir 配合物催化的苄基和芳基 CH 硼化的动力学研究表明,芳基 CH 硼化速率随着 Ir 催化剂金属中心电子密度的降低而降低,但苄基 CH 硼化速率对Ir 催化剂金属中心的电子密度。动力学和计算研究表明,这两种硼酸化反应对金属中心的电子密度程度的反应不同,因为它们发生在不同的转换限制步骤中。已知芳基
