  Indole Synthesis by Controlled Carbolithiation of o-Aminostyrenes

  摘要：

  An effective synthesis of the functionalized indole ring system has been developed from substituted o-aminostyrene starting material. Our methodology involves a novel cascade reaction sequence of alkyllithium addition to the styrene double bond and subsequent trapping of the intermediate organolithium with a suitable electrophile, followed by an in situ ring closure and dehydration to generate the indole ring. This new reaction sequence allows for the introduction of molecular diversity at all positions on the indole scaffold. The procedure was shown to be successful with a range of both C and N substituents on the o-aminostyrenes. The reaction sequence was tolerant to the reactivity range of alkyllithiums such as tert-, sec-, and n-butyllithium. The electrophiles used were DMF, which generated indole products with C-2 unsubstituted, and nitriles, which incorporated the nitrile substituent at C-2. The o-aminostyrene starting materials were generated by a Pd-catalyzed cross-coupling reaction of a vinyl boronic acid equivalent with the readily available substituted o-bromoanilines.

  A novel synthetic approach to diversely functionalized indoles is described. Boc-protected ortho-aminostyrenes undergo an alkyllithium addition reaction, thereby generating a lithiated intermediate, which upon reaction with specific electrophiles sets up a cascade reaction process between the reacted electrophile and ortho-amino substituent, facilitating an in situ ring closure, followed by dehydration

  oncology. These compounds have high affinity for calcium ions (Ca2+) and therefore target bone mineral, where they appear to be internalized selectively by bone-resorbing osteoclasts and inhibit osteoclast function. They are extensively used in healthcare, however they are affected by severe side effects; pharmacological properties of bisphosphonates depend on their molecular structure, which is frequently

  双膦酸盐是最重要的一类抗吸收剂，可用于抗破骨细胞介导的骨质流失，最近在肿瘤学中也是如此。这些化合物对钙离子（Ca 2+）具有高亲和力，因此靶向骨矿物质，在这些地方矿物质似乎被骨吸收破骨细胞选择性内化并抑制破骨细胞功能。它们广泛用于医疗保健中，但是会受到严重副作用的影响。双膦酸酯的药理特性取决于其分子结构，这通常是肠道吸收差和分布低的原因。在这项工作中，我们合成了六种具有可变取代的吲哚部分的新型双膦酸酯化合物，以评估它们在PE / CA-PJ15细胞中的细胞外和细胞内钙螯合能力。初步的在硅片和体外ADME研究还进行和结果表明，吲哚部分在细胞渗透性和代谢性质中起重要作用。
