Sunlight-driven synthesis of γ-diketones via oxidative coupling of enamines with silyl enol ethers catalyzed by [Ru(bpy)3]2+

A photosensitizer [Ru(bpy)3]2+ catalyzes oxidative coupling reaction of enamines with silyl enol ethers under visible light irradiation by a Xe lamp or sunlight to produce γ-diketones. A 2e-oxidation process involved in this reaction is achieved by a combination of the photoexcited [Ru(bpy)3]2+ species and duroquinone, a 2e-acceptor.
Regioselective assembly of fused pyrazole-azepine heterocycles: Synthesis of the 5-HT7 antagonist 1-benzyl-3-(4-chlorophenyl)-1,4,5,6,7,8-hexahydropyrazolo[3,4-d]azepine

The synthesis of the 5-HT7 antagonist 1-benzyl-3-(4-chlorophenyl)-1,4,5,6,7,8-hexahydropyrazolo[3,4-d]azepine is described using a regioselective assembly of a pyrazole ring fused to an azepine ring. Two different approaches were examined for the construction of the fused pyrazole-azepine heterocyclic core. These were based on the timing and method of installation of the appended aryl ring and construction
5-HT 7拮抗剂1-苄基-3-(4-氯苯基)-1,4,5,6,7,8-六氢吡唑并[3,4- d ]氮杂的合成是使用a的区域选择性组装来描述的与吡咯环稠合的吡唑环。检查了两种不同的方法用于稠合吡唑-氮杂杂环核心的构建。这些基于附接的芳基环的安装时间和方法以及稠合杂环的构造。该团队着重研究了一种以钯偶联反应为特征的途径,该反应通过三氟甲磺酸吡唑引入芳环,并进行选择性烷基化以设定苄基在吡唑氮上的位置。这导致1的可扩展综合 (JNJ-18038683)允许发现小组选择并提升临床候选人。
