  Construction of 3-arylpropylamines using Heck arylations. The total synthesis of cinacalcet hydrochloride, alverine, and tolpropamine

  摘要：

  New synthetic routes toward the commercial drugs cinacalcet hydrochloride, alverine, and tolpropamine were developed using a Heck-Matsuda arylation as the key-step. Several reaction conditions were evaluated for the Heck-Matsuda reaction using allylamine derivatives and arenediazonium salts. For cinacalcet hydrochloride, N-formylamide provided the best result, furnishing the synthetic target in a very high overall yield (75% over five steps). For alverine, the best results were obtained using a double Heck-Matsuda strategy, providing alverine in an excellent overall yield (69%) from N-acetyl diallylamine in three steps. Tolpropamine was synthesized in a 46% yield over five steps using an efficient reductive Heck-Matsuda arylation between p-bromo-methylcinnamate with 3-chloro tolyldiazonium salt, generating the beta,beta-diaryl propionate that was converted to tolpropamine.

  β-烯胺酮偶氮偶联后新戊酰基的重氮交换和迁移

  摘要：

  4,4-Dimethyl-1-methylamino-1-phenyl-2-(已取代的 phenyldiazenyl)pent-1-en-3-ones（在 4,4-dimethyl-1-methylamino-1-phenylpent-1 的偶氮偶联后制备-en-3-one 6a 与相应的重氮苯四氟硼酸盐）与另一分子取代的重氮四氟硼酸盐（在二氯甲烷中，在无水醋酸钠存在下）反应，形成取代的 4,4-双（取代的苯基二氮烯基）衍生物 8. 第二个偶氮耦合是可逆的。衍生物 8 经历重氮离子的反向裂解或 [1,3] sigmatropic 重排，形成取代的甲氮烷 9。在连续使用两种不同的四氟硼酸重氮盐的情况下，亲电性较低的基团更容易分裂。产物9的结构通过X射线、1H、13C、19F 和 15N NMR 和 MALDI HRMS 分析。甲脒 9 表现出与新戊酰基相邻的苯基的迁移率降低，导致质子和碳原子

  Gold(I)-catalyzed cross-coupling reactions of aryldiazonium salts with organostannanes are described. This redox neutral strategy offers an efficient approach to diverse biaryls, vinyl arenes and arylacetylenes. Monitoring the reaction with NMR and ESI-MS provided strong evidence for the in situ formation of Ph3PAuIR (R = aryl, vinyl and alkynyl) species which is crucial for the activation of aryldiazonium

  aqueous solution, the reduction steps have been investigated by means of correlation analyses of the effects of diazonium ion substitution on the rates of reduction. For simple hydroxylation, a change of behaviour between diazonium ions substituted by electron donor groups and those substituted by electron acceptor groups is interpreted as a change within an inner-sphere process from rate-determining electron

  对于桑德迈尔水溶液中的羟基化和氯化反应，通过相关分析重氮离子取代对还原速率的影响，研究了还原步骤。对于简单的羟基化，被电子给体基团取代的重氮离子与被电子受体基团取代的重氮离子之间的行为变化被解释为内球过程中从速率确定电子转移到反应物速率确定缔合的变化。相比之下，对于柠檬酸盐促进的羟基化，类似的行为变化可解释为内层和外层电子转移之间的变化。对于氯化作用，在所检查的取代基范围内没有机理上的变化，但其行为方式与内球机理一致。根据重氮离子取代和催化剂连接对各种反应性氧化还原对的还原电势和自交换速率的影响，合理化了各种行为方式。重氮离子的还原反应和其他亲电反应的比较相关性分析用于支持关于Sandmeyer还原步骤的高级论证。建议铜我还原剂反应经由亲核桥连配体的重氮Ñ β以得到瞬变ž-adducts其为前体配合物和活化用于电子转移包括关于N-N键的旋转。

  One‐pot sequential Heck reduction–cyclization (HRC) reactions leading to the synthesis of substituted 2‐quinolones have been developed by using a heterogeneous or mixed homogeneous/heterogeneous multitask palladium catalyst with charcoal as a support. The whole sequence occurs under very mild conditions without the need for additives (ligand or base) by taking advantage of the high reactivity of aryldiazonium

  通过使用木炭作为载体的异相或混合均相/非均相多任务钯催化剂，已经开发出了导致合成2-喹诺酮的单锅顺序Heck还原-环化（HRC）反应。通过利用芳基重氮盐的高反应活性作为“超级亲电子试剂”，整个序列在非常温和的条件下发生，而无需添加剂（配体或碱）。循环实验表明，重复使用的非均相Pd 0 / C催化剂不能促进另一个HRC序列，但是对于加氢，加氢脱卤以及氢解反应仍然具有很高的活性。

  Direct C5 (hetero)arylation of uracil and uridine substrates with (hetero)aryl diazonium salts under photoredox catalysis with blue light was reported. The coupling proceeds efficiently with diazonium salts and heterocycles in good functional group tolerance at room temperature in aqueous solution without transition-metal components. A plausible radical mechanism has been proposed.
