The present invention relates to a series of substituted para-biphenyloxymethyl dihydro oxazolopyrimidinones of formula (I) 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, cognition deficit disorders, convulsions, anxiety, depression, migraine, pain, sleep disorders and emesis.
significance and in great demand. Among these, C–H bondsilylation provides a powerful and straightforward synthetic method to form diverse silacycles in an atom- and step-economical fashion. However, C–H bondsilylation has not been used to access any six-membered silicon-bridged π-conjugated scaffolds and enantioselective six-membered C–H silylation has never been presented. Herein, we successfully
C / Si转换策略已被认为是发现药物和材料的有用和高效的策略。因此,开发访问各种硅杂环的方法学具有重要意义和需求。其中,C–H键甲硅烷基化提供了一种强大而直接的合成方法,可以以原子经济和分步经济的方式形成各种硅杂环。但是,尚未使用C–H键甲硅烷基化来获得任何六元硅桥π-共轭支架,并且从未提出对映选择性的六元C–H甲硅烷基化。在这里,我们通过C–H键甲硅烷基化成功地获得了多种多样的六元π共轭二苯并恶唑啉,并研究了它们的光物理性质。此外,我们认识到对映选择性六元C H硅烷化可以直接提供具有高ee(高达95%ee)的平面手性茂金属恶二唑烷。我们还证明了通过各种其他转化,二苯并恶唑啉和平面手性茂金属稠合的苯并恶唑啉作为有价值的合成中间体的合成有用性。此外,利用我们的方法设计并快速构建了六元硅桥梯π共轭体系。还详细评估了“异构化”和“硅”对分子几何形状和光物理性质的影响。利用我们的方法设计并快速构

)-H Alkynylation/Annulation of 2-Phenylphenols with Haloalkynes Using Phenolic Hydroxyl as the Traceless Directing Group
An efficient, palladium(II)‐catalyzed, C(sp2)‐H alkynylation/annulation of 2‐phenylphenols with haloalkynes for the synthesis of substituted 6‐methylene‐6H‐dibenzo[b,d]pyrans is reported. This protocol features a traceless directing group strategy, unique regioselectivity and mild reaction conditions. Significantly, preliminary mechanistic studies suggest that the sequential C(sp2)‐H alkynylation and

This note describes the efficient and highly regioselectivesynthesis of 2-(2′-alkenylphenyl)phenol derivatives via palladium-catalyzed 2′-alkenylation of 2-arylphenols directed by the phenolic hydroxyl group using benzoquinone as the oxidant in an atmosphere of air. This reaction can tolerate a series of functional groups and provides the alkenylation products regio- and stereoselectively in moderate
