  Synthesis and Spectroscopic Comparison of the Eight Methyl-2,3’-bipyridyls and Identification of a Hoplonemertine Alkaloid as 3-Methyl-2,3’-bipyridyl

  摘要：

  The pyridyl ring is frequently found in natural products and drugs. While bipyridyls have served as useful scaffolds for development of industrial and pesticidal chemicals, their biological properties are still not well understood. Only 2,3'-bipyridyl, of the six isomeric bipyridyls, has been reported as a natural product in tobacco plants and in a hoplonemertine marine worm, Amphiporus angulatus (Aa), which uses its pyridyl alkaloid-rich venom to paralyze its crustacean prey and chemically defend itself against predators. Here we report for the first time the synthesis and spectroscopic properties of all eight possible methyl 2,3'-bipyridyl isomers and use this data to identify a trace alkaloidal constituent of Aa as 3-methyl-2,3'-bipyridyl. This is only the second reported instance of a methyl-bipyridyl being found as a natural product, the first being the tobacco alkaloid 5-methyl-2,3'-bipyridyl.

  aliphatic substrates for selective C(sp3)–H bond borylations. Heterocyclic molecules are selectively borylated using the inherently elevated reactivity of the C–H bonds. A number of late-stage C–H functionalization have been described using the same catalysts. Furthermore, we show that one of the catalysts could be used even in open air for the C(sp2)–H and C(sp3)–H borylations enabling the method more general

  在这里，我们描述了一类新的 C-H 硼化催化剂的发现及其在芳族、杂芳族和脂肪族系统的区域选择性 C-H 硼化中的应用。新催化剂具有 Ir-C(噻吩基) 或 Ir-C(呋喃基) 阴离子配体，而不是标准 C-H 硼化条件中使用的二胺型中性螯合配体。据报道，这些新发现的催化剂的使用对不同种类的芳烃底物显示出优异的反应性和邻位选择性，并具有高分离产率。此外，该催化剂被证明对大量脂肪族底物的选择性 C(sp 3)–H 键硼化。杂环分子利用 C-H 键固有的高反应性选择性地硼化。已经使用相同的催化剂描述了许多后期 C-H 功能化。此外，我们表明其中一种催化剂甚至可以在露天用于 C(sp 2 )-H 和 C(sp 3 )-H 硼酸化，从而使该方法更加通用。初步的机理研究表明，活性催化中间体是 Ir(bis)boryl 络合物，连接的配体作为双齿配体。总的来说，这项研究强调了新型 C-H 硼酸化催化剂的发现，这些催化剂应该在
