sought to mimic this coupling by using stoichiometric oxidants. However, all approaches to date have suffered from low yields or the formation of undesired regioisomers. Electrochemistry would represent a sustainable alternative in this respect but all attempts to accomplish an electrochemical synthesis of thebaine have failed so far. Herein, a regio‐ and diastereoselective anodic coupling of 3′,4′,5′‐trioxygenated
蒂巴因的生物合成是基于(R)-网红的区域选择性,分子内,氧化偶联。几十年来,化学家一直试图通过使用化学计量的氧化剂来模拟这种偶联。然而,迄今为止,所有方法都遭受了低产率或不期望的区域异构体形成的困扰。在这方面,电化学将是一种可持续的选择,但是到目前为止,完成蒂巴因的电化学合成的所有尝试都失败了。本文介绍了3',4',5'-三加氧的月桂肌苷衍生物的区域和非对映选择性阳极偶联,最终使电化学方法可接近(-)-蒂巴因。
