Asymmetric hydrogenation catalyzed by a rhodium complex of (R)-(tert-butylmethylphosphino)(di-tert-butylphosphino)methane: scope of enantioselectivity and mechanistic study.

Ilya D Gridnev et al.

Journal of the American Chemical Society, 130(8), 2560-2572 (2008-02-02)

The rhodium complex of (R)-(tert-butylmethylphosphino)(di-tert-butylphosphino)methane used in Rh-catalyzed asymmetric hydrogenation of representative substrates 3-14 demonstrated high catalytic activity coupled with wide scope and nearly perfect enantioselectivity. Mechanistic studies (NMR and DFT computations) were carried out in order to investigate the

Highly selective asymmetric hydrogenation using a three hindered quadrant bisphosphine rhodium catalyst.

Garrett Hoge et al.

Journal of the American Chemical Society, 126(19), 5966-5967 (2004-05-13)

A concise synthesis of both enantiomers of ligand 2 and rhodium complex 5 is presented. The crux of the synthesis is a chiral HPLC separation of the enantiomers of 4. Rhodium complex 5 possesses three hindered quadrants in the steric

Recent Advances in Asymmetric Hydrogenation of Tetrasubstituted Olefins.

Stefan Kraft et al.

Journal of the American Chemical Society, 139(34), 11630-11641 (2017-08-12)

The asymmetric hydrogenation of tetrasubstituted olefins provides direct access to very useful biological molecules and intermediates. The development of the technology has been slow, due in part to the synthetic challenges involved in developing chiral catalysts for a successful asymmetric

Highly enantioselective asymmetric hydrogenation of beta-acetamido dehydroamino acid derivatives using a three-hindered quadrant rhodium catalyst.

He-Ping Wu et al.

Organic letters, 6(20), 3645-3647 (2004-09-25)

[reaction: see text] A previously reported three-hindered quadrant chiral ligand and its corresponding rhodium complex provide high enantioselectivity for the asymmetric hydrogenation of beta-acetamido dehydroamino acid substrates. Both (E)- and (Z)-substrates are hydrogenated with high enantioselectivity in all of the
