许多适当取代的吡啶基或苯基用作胺的电化学氧化的特别有利的活化基序。这些基团为跨众多活化基团和胺支架的叔胺电化学α-官能化提供了一种通用、温和的方法。值得注意的是,该方法适应了前所未有的亲核试剂类别,允许将不同的官能团引入易于制备的胺底物中。然后通过不对称双功能化、N-吡啶胺与其他活性胺的位点选择性功能化、ivosidenib 的正式合成以及 FDA 批准的药物或天然产物底物的多样化的应用来证明该方法的实用性。

There is disclosed a process for performing an isolated Pd(II) mediated oxidation reaction electrochemically. The inventive process is performed on an electrode array device having a plurality of separately addressable electrodes. Preferably, the Pd(II) mediated oxidation is a Wacker reaction. Specifically, there is disclosed a process for conducting an isolated Pd(II) mediated oxidation on a plurality of electrodes, comprising providing an electrode array device having a plurality of electrodes with a conductive electrode surface and a matrix or coating material over the electrodes surfaces; providing a solution bathing the electrode array matrix or coating material and electrode surfaces, wherein the solution comprises a transition metal species and a confining agent; and biasing one or a plurality of electrodes (“selected electrode or electrodes”) with a voltage or current to regenerate the transition metal species required for the isolated Pd(II) mediated oxidation, whereby the confining agent limits diffusion of the transition metal species to a volume surrounding each selected electrode surface.

1H NMR and isothermaltitrationcalorimetry (ITC). In chloroform solvent, hydrogen-bonding to anions is accompanied by downfield shifts in the amide NH protons of the fluorinated receptors and by evolution of heat. Association constants for 1:1 complexation (Kassoc) are >1000 M−1. An analogous hydrocarbon receptor binds weakly to anionic guests (Kassoc < 50 M−1). Abinitiocalculations indicate that
