alkylation of γ-C(sp(3))-H bonds of picolinamide-protected aliphatic amine substrates with primary alkyl iodides via palladium catalysis. Ag(2)CO(3) and dibenzyl phosphate, (BnO)(2)PO(2)H, are critical promoters of this reaction. These reactions provide a convenient and straightforward method for the preparation of high-value N-containing products from readily available amine and alkyl iodide precursors
我们报告了一种通过钯催化用伯烷基碘对吡啶酰胺保护的脂肪胺底物的 γ-C(sp(3))-H 键进行烷基化的有效方法。Ag(2)CO(3) 和磷酸二苄基酯 (BnO)(2)PO(2)H 是该反应的关键促进剂。这些反应为从容易获得的胺和烷基碘前体制备高价值含氮产品提供了一种方便和直接的方法。
