  Controlled-Deactivation Cannabinergic Ligands

  摘要：

  We report an approach for obtaining novel cannabinoid analogues with controllable deactivation and improved druggability. Our design involves the incorporation of a metabolically labile ester group at the 2'-position on a series of (-)-Delta(8)-THC analogues. We have sought to introduce benzylic substituents a to the ester group which affect the half-lives of deactivation through enzymatic activity while enhancing the affinities and efficacies of individual ligands for the CB1 and CB2 receptors. The 1'-(S)-methyl, 1'-gem-dimethyl, and 1'-cyclobutyl analogues exhibit remarkably high affinities for both CB receptors. The novel ligands are susceptible to enzymatic hydrolysis by plasma esterases in a controllable manner, while their metabolites are inactive at the CB receptors. In further in vitro and in vivo experiments key analogues were shown to be potent CB1 receptor agonists and to exhibit CBI-mediated hypothermic and analgesic effects.

  in the selective manipulation of functional groups (chemoselectivity) in organic synthesis have historically been overcome either by using reagents/catalysts that tunably interact with a substrate or through modification to shield undesired sites of reactivity (protecting groups). Although electrochemistry offers precise redox control to achieve unique chemoselectivity, this approach often becomes challenging

  有机合成中选择性操纵官能团（化学选择性）的挑战历来通过使用与底物可调节相互作用的试剂/催化剂或通过修饰以屏蔽不需要的反应位点（保护基团）来克服。尽管电化学提供了精确的氧化还原控制以实现独特的化学选择性，但在存在多种氧化还原活性功能的情况下，这种方法通常变得具有挑战性。从历史上看，电合成几乎完全使用直流电（DC）进行。相比之下，众所周知，应用交流电 (AC) 可以在分析规模上显着改变反应结果，但很少被战略性地用于复杂的制备有机合成。在这里，我们展示了如何使用方波来传递电流——快速交替极性（rAP）——能够控制羰基化合物化学选择性还原中的反应结果，这是最广泛使用的反应流形之一。观察到的反应性不能使用直流电解或化学试剂来重现。这种控制化学选择性的新方法所带来的合成价值在手性辅助去除等经典反应问题和PROTAC合成等前沿药物化学主题的背景下得到了生动的体现。

  日期：2017.3.13

  The total synthesis of four actinoranone stereoisomers led to unambiguous assignment of relative and absolute stereochemistry of the natural product. Key features of the convergent, fully stereocontrolled route include the use of a Negishi carbozirconation/iodination, a Friedel–Crafts cyclization, a Felkin‐controlled addition reaction, a Mitsunobu reaction, and a late‐stage C−H oxidation.

  四种肌动龙酮立体异构体的总合成导致天然产物的相对和绝对立体化学的明确分配。收敛的，完全立体控制的路线的关键特征包括使用Negishi碳羰基化/碘化，Friedel-Crafts环化，Felkin控制的加成反应，Mitsunobu反应和后期C-H氧化。
