A rhodium-catalyzed reaction of N-hydroxyanilines with diazo compounds to produce α-imino esters was developed. Distinct from the commonly accepted 1,2-H transfer for normal X-H insertion reactions, density functional theory calculations indicate that this transformation proceeds via a novel rebound hydrolysis mechanism. Furthermore, a three-component reaction was explored to synthesize highly functionalized β-lactams in good yields and diastereoselectivities.

, p. 20352 - 20360 (2015/12/04)
A series of zirconium complexes bearing amine-bridged bis(phenolato) ligands of different steric and electronic properties have been synthesized, and their activities in catalyzing intermolecular hydroamination reactions have been studied and compared. In
Synthesis of group 4 metal complexes stabilized by an amine-bridged bis(phenolato) ligand and their catalytic behavior in intermolecular hydroamination reactions
Sun, Qiu,Wang, Yaorong,Yuan, Dan,Yao, Yingming,Shen, Qi
, p. 994 - 1001 (2014/03/21)
Zirconium and titanium complexes 1 and 2, bearing an amine-bridged bis(phenolato) ligand, have been synthesized and characterized. Although 1 and 2 were inactive in catalyzing intermolecular hydroamination reactions, cationic complexes generated in situ f
Au(I)-catalyzed highly efficient intermolecular hydroamination of alkynes
Mizushima, Eiichiro,Hayashi, Teruyuki,Tanaka, Masato
