  摘要：

  C-CN键的选择性氢解可让化学家利用氰基的邻位导向能力，α-CH酸度和吸电子能力进行合成操作。我们已经发现，通过使用镍催化剂，仅在1 bar的氢气下就可以芳基和脂肪族氰化物进行氢解。该方案适用于芳基氰化物指导的官能化反应和苄基氰化物的α-取代。

  Remote para-C–H Functionalization of Arenes by a D-Shaped Biphenyl Template-Based Assembly

  摘要：

  Site-selective C-H functionalization has emerged as an efficient tool in simplifying the synthesis of complex molecules. Most often, directing group (DG)-assisted metallacyde formation serves as an efficient strategy to ensure promising regioselectivity. A wide variety of ortho- and meta-C-H functionalizations stand as examples in this regard. Yet despite this significant progress, DG-assisted selective para-C-H functionalizalion in arenes has remained unexplored, mainly because it involves the formation of a geometrically constrained metallacyclic transition state. Here we report an easily recyclable, novel Si-containing biphenyl-based template that directs efficient functionalization of the distal p-C-H bond of toluene by forming a D-shaped assembly. This DG allows the required flexibility to support the formation of an oversized pre-transition state. By overcoming electronic and steric bias, para-olefination and acetoxylation were successfully performed while undermining oand m-C-H activation. The applicability of this D-shaped biphenyl template-based strategy is demonstrated by synthesizing various complex molecules.

  Highly substituted fluorenones are readily prepared in mostly fair to good yields via metal- and additive-free TBHP-promoted cross-dehydrogenative coupling (CDC) of readily accessible N-methyl-2-(aminomethyl)biphenyls and 2-(aminomethyl)biphenyls. This methodology is compatible with numerous functional groups (methoxy, cyano, nitro, chloro, and SEM and TBS-protective groups for phenols) and was further

  novel quinoxaline heterocycle containing angiotensin II receptor antagonist analogs were prepared. This heterocycle was coupled to the biphenyl moiety via an oxygen atom linker instead of a carbon atom. Many of these analogs exhibit very potent activity and long duration of effect. Interestingly, the N-oxide quinoxaline analog was more potent than the nonoxidized quinoxaline as in the comparison of

  regioselectivity. Often, the high thermal energy required to promote olefination leads to multiple site functionalizations. To this aim, we established a photoredox catalytic system constituting a merger of palladium/organo-photocatalyst (PC) that forges oxidative olefination in an explicit regioselective fashion with diverse arenes and heteroarenes. Visible light plays a significant role in executing “regioresolved”

  藤原-森谷反应对当代 C-H 激活方案的出现做出了深远的贡献。尽管传统方法在不同领域具有适用性，但相关的反应性和区域选择性问题使其变得多余。该示例性反应的复兴需要开发一种机械范式，该范式将同时控制反应性和区域选择性。通常，促进烯烃化所需的高热能导致多位点官能化。为此，我们建立了一个光氧化还原催化系统，该系统由钯/有机光催化剂 (PC) 的合并组成，该系统以显式的区域选择性方式与多种芳烃和杂芳烃进行氧化烯化。可见光在不需要银盐和热能的情况下在执行“区域分解”的藤原-森谷反应中起着重要作用。该催化系统还可以在各自的导向基团 (DGs) 的帮助下进行近端和远端烯烃化，这需要该协议在参与整个 C(sp) 光谱方面的多功能性2 )-H烯化。此外，通过后期功能化简化天然产物、手性分子、药物的合成和多样化，强调了这种可持续协议的重要性。这种区域选择性转化的光诱导实现是通过控制反应和动力学研究机械地建立的。
