Monodentate phosphoramidites based on BINOL or substituted BINOL are excellent ligands for the rhodium-catalysed asymmetric hydrogenation of olefins. Very high enantioselectivities were obtained with MonoPhos (7a) the simplest member of this class, a

Publikováno v: Synlett. :2667-2669
An easy 2-step method for the synthesis of the water-soluble singlet oxygen trap AES has been developed. The method is based on a novel Heck reaction with sodium vinylsulfonate followed by vinyl hydrogenation. It is shownthat the Heck product AVS is

Publikováno v: Organic Process Research & Development, 11(3). AMER CHEMICAL SOC INC
An asymmetric hydrogenation process for the α-isopropyl dihydrocinnamic acid derivative 2, an intermediate for the renin inhibitor aliskiren (4), has been developed using a rhodium catalyst ligated with a chiral monodentate phosphoramidite and a non

Instant Ligand Libraries. Parallel Synthesis of Monodentate Phosphoramidites and in Situ Screening in Asymmetric Hydrogenation
Autor: and André H. M. de Vries, Johannes G. de Vries, Jeroen A. F. Boogers, Laurent Lefort
Publikováno v: Organic letters, 6(11). AMER CHEMICAL SOC INC
Chiral phosphoramidites have been identified as excellent ligands for various metal-catalyzed enantioselective transformations. Taking advantage of their easy preparation and modular nature, we designed a fully automated protocol for the parallel pre
