Ruthenium(II)-Catalyzed <i>Ortho</i>-C–H Alkylation of Naphthylamines with Diazo Compounds for Synthesis of 2,2-Disubstituted π-Extended 3-Oxindoles in Water
Ruthenium(II)-catalyzed ortho-C–H alkylation of naphthylamines with diazocompounds for the synthesis of 2,2-disubstituted π-extended 3-oxindoles has been developed. The method represents the first example of C–H alkylation via carbenoid insertion in water as a sustainable solvent. The procedure includes an inexpensive ruthenium catalyst as well as aqueous media and results in the release of benign

Iridium‐catalyzed C−H activation and cyclization of naphthalen‐1‐amines with diazo compounds leading to naphtho[1,8‐bc]pyridines have been developed. Different from the previous free‐amine‐directed C−H functionalization with diazo compounds that relied on the coordination of lone pair electrons or in situ formation of imine, this transformation passes through a five‐membered iridacycle intermediate containing an
已经开发了铱催化的CH-1活化和萘-1-胺与重氮化合物的环合反应,从而生成萘[1,8- bc ]吡啶。与以前的重氮化合物基于孤对电子的配位或亚胺的原位形成的重氮化合物的游离胺定向的CH官能化不同,该转化过程通过包含N-Irσ-键的五元iridacycle中间体进行。 。它为在温和条件下合成有用的各种萘并[1,8- bc ]吡啶衍生物提供了另一种方法。

Pd-catalyzed selective amine-oriented C8-H bond functionalization/N-dealkylative carbonylation of naphthyl amines has been achieved. The aminegroup from dealkylation is proposed to be the directing goup to promote this process. It...
