The arylation of 2-alkyl aziridines by nucleophilic ring-opening or transition-metal-catalyzed cross-coupling enables facile access to biologically relevant β-phenethylamine derivatives. However, both approaches largely favor C–C bond formation at the less-substituted carbon of the aziridine, thus enabling access to only linear products. Consequently, despite the attractive bond disconnection that
通过亲核开环或过渡金属催化的交叉偶联对 2-烷基氮丙啶进行芳基化,可以轻松获得生物学相关的 β-苯乙胺衍生物。然而,这两种方法很大程度上都有利于在氮丙啶的取代较少的碳上形成 C-C 键,从而只能获得线性产物。因此,尽管它引起了有吸引力的键断裂,但从 2-烷基氮丙啶合成支链芳基化产物仍然无法实现。在此,我们解决了这一长期存在的挑战,并报告了 2-烷基氮丙啶与芳基碘化物的首次支链选择性交叉偶联。这种独特的选择性是通过钛/镍双催化系统实现的。我们通过双重方法证明了该方法的稳健性:用于探测官能团耐受性的附加筛选活动和用于研究每个偶联伙伴的局部空间和电子分布对反应性的影响的特征驱动底物范围。此外,这种特征驱动的底物范围的多样性使得能够生成指导机械理解的预测反应模型。机理研究表明,支链选择性源于 Ti III诱导的氮丙啶自由基开环。

Although all kinases share the same ATP binding pocket, subtle differences in the residues that form the pocket differentiate individual kinases' affinity for ATP competitive inhibitors. We have found that by introducing a single methyl group, the selectivity of our MERTK inhibitors over another target, FLT3, was increased up to 1000-fold (compound 31). Compound 19 was identified as an in vivo tool compound with subnanomolar activity against MERTK and 38-fold selectivity over FLT3 in vitro. The potency and selectivity of 19 for MERTK over FLT3 were confirmed in cell-based assays using human cancer cell lines. Compound 19 had favorable pharmacokinetic properties in mice. Phosphorylation of MERTK was decreased by 75% in bone marrow leukemia cells from mice treated with 19 compared to vehicle-treated mice.
