Enantioselective hydrogenation of α-dehydroamino acid esters catalyzed by rhodium complexes with chiral bisaminophosphine ligands
Sun, Xianfeng,Li, Wei,Zhou, Le,Zhang, Xumu
, p. 1150 - 1154 (2010)
A highly efficient strategy for the synthesis of a series of chiral bisaminophosphine ligands was well established with several remarkable features. The synthetic utility of these ligands was explored for rhodium-catalyzed asymmetric hydrogenations of α-d
Highly diastereoselective synthesis of atropisomeric bridged P,N-ligands and their applications in asymmetric suzuki-miyaura coupling reaction

, p. 2395 - 2402 (2012)
Three novel atropisomeric bridged P,N-ligands were prepared using a highly efficient central-to-axial transfer strategy as the protocol. The new chiral ligands were successfully applied in the palladium-catalyzed asymmetric Suzuki-Miyaura coupling reaction, Up to 98% yield and 82% ee were obtained in the enantioselective synthesis of axially chiral biarylphosphonates.

Axial [6,6′-(2,4-pentadioxy)]-1,1′-biphenyl-2,2′-diamine (PD-BIPHAM): practical synthesis and applications in asymmetric hydrogenation
Wang, Chun-Jiang,Xu, Zhong-Ping,Wang, Xiang,Teng, Huai-Long
, p. 3702 - 3706 (2010)
A rapid, reliable, and atom-economical procedure for the novel axially biphenyl diamine, (R,R,Sax)-PD-BIPHAM 1, has been developed successfully by using highly efficient central-to-axial transformation strategy. The attractive feature of this m
Axial chirality control by 2,4-pentanediol for the alternative synthesis of c3-tunephos chiral diphosphine ligands and their applications in highly enantioselective ruthenium-catalyzed hydrogenation of β-keto esters
Sun, Xianfeng,Li, Wei,Hou, Guohua,Zhou, Le,Zhang, Xumu
, p. 2553 - 2557 (2009)
A highly efficient strategy for the synthesis of a series of C 3*-TunePhos chiral diphosphine ligands was well established with several remarkable features. The synthetic utility of these ligands was explored for the ruthenium-catalyzed asymmetric hydrogenation of β-keto esters. Up to 99% ee values were achieved for the enantioselective synthesis of β-hydroxy acid derivatives, which are very important chiral building blocks for the synthesis of a variety of natural products and biologically active molecules.
