cross-couple unactivated secondary alkyl iodides with various N-, O-, and C-based nucleophiles. This strategy harnesses the ability of photoredox-generated phenyl radicals to mediate halogen-atom transfer (XAT) and convert alkyl iodides into the corresponding radicals. These species engage in a second catalytic cycle, mediated by copper, which enables C–N/O/C bond formation with the various nucleophiles
在这里,我们报告了一种工具箱策略,用于将未活化的仲烷基碘与各种基于 N、O 和 C 的亲核试剂交叉偶联。该策略利用光氧化还原产生的苯基自由基介导卤素原子转移 (XAT) 并将烷基碘转化为相应自由基的能力。这些物质参与由铜介导的第二个催化循环,从而能够与各种亲核试剂形成 C-N/O/C 键。

Stearoyl-CoA desaturase 1 (SCD1) catalyzes the committed step in the biosynthesis of monounsaturated fatty acids from saturated, long-chain fatty acids. Studies with SCD1 knockout mice have established that these animals are lean and protected from leptin deficiency-induced and diet-induced obesity, with greater whole body insulin sensitivity than wild-type animals. In this work, we have discovered a series of potent, selective, orally bioavailable SCD1 inhibitors based on a known pyridazine carboxamide template. The representative lead inhibitor 28c also demonstrates excellent cellular activity in blocking the conversion of saturated long-chain fatty acid-CoAs (LCFA-CoAs) to monounsaturated LCFA-CoAs in HepG2 cells.

A series of structurally novel stearoyl-CoA desaturase1 (SCD1) inhibitors has been identified via molecular scaffold manipulation. Preliminary structure-activity relationship (SAR) studies led to the discovery of potent, and orally bioavailable piperidine-aryl urea-based SCD1 inhibitors. 4-(2-Chlorophenoxy)-N-[3-(methyl carbamoyl)phenyl]piperidine-1-carboxamide 4c exhibited robust in vivo activity with dose-dependent desaturation index lowering effects.
