  Efficient Synthesis of a GABA_A α_2,3-Selective Allosteric Modulator via a Sequential Pd-Catalyzed Cross-Coupling Approach

  摘要：

  A practical synthesis of 2- [3-(4-fluoro-3-pyridin-3-yl-phenyl)-imidazo [1,2-a] pyrimidin-7-yl] -propan-2-ol (1), an oral GABA(A) alpha(2/3)-selective agonist, is described. The five-step process, which afforded 1 in 40% overall yield, included imidazopyrimidine 2 and pyridine boronic acid 4 as key fragments. The synthesis is highlighted by consecutive Pd-catalyzed coupling steps to assemble the final free base 1 in high yield and regioselectivity. A novel method for Pd removal in the final step is also described.

  A class of 3-phenylimidazo[1,2-&agr;]pyrimidine derivatives, substituted at the meta position of the phenyl ring by an optionally substituted aryl or heteroaryl group which is directly attached or bridged by an oxygen atom or a —NH— linkage, and further substituted on the phenyl ring by alkyl, trifluoromethyl, alkoxy or one or two halogen atoms, especially fluoro, are selective ligands for GABA A receptors, in particular having good affinity for the &agr;2 and/or &agr;3 and/or &agr;5 subunit thereof, and are accordingly of benefit in the treatment and/or prevention of adverse conditions of the central nervous system, including anxiety, convulsions and cognitive disorders.

  一类3-苯基咪唑[1,2-&agr;]嘧啶衍生物，苯环的间位被取代，取代基可以是直接连接或通过氧原子或-NH-键桥接的取代芳基或杂环芳基，苯环上进一步被取代为烷基，三氟甲基，烷氧基或一个或两个卤素原子，特别是氟，是GABAA受体的选择性配体，特别是对其中的&agr;2和/或&agr;3和/或&agr;5亚基具有良好的亲和力，因此对于治疗和/或预防中枢神经系统的不良症状，包括焦虑，惊厥和认知障碍具有益处。
