PipPhos and MorfPhos: Privileged monodentate phosphoramidite ligands for rhodium-catalyzed asymmetric hydrogenation
Heiko Bernsmann,M.P. van den Berg,Robert Hoen,Adriaan J. Minnaard,Gerlinde Mehler,Manfred T. Reetz,de Johannes Vries,Bernard Feringa +7 more
TL;DR: A library of 20 monodentate phosphoramidite ligands has been prepared and applied in rhodium-catalyzed asymmetric hydrogenation, resulting in the identification of two ligands, PipPhos and MorfPhos, that afford excellent and in several cases unprecedented enantioselectivities in the hydrogenation of N-acyldehydroamino acid esters.
Journal ArticleDOI
Rhodium-catalyzed addition of arylboronic acids to isatins
Journal ArticleDOI
Application of monodentate secondary phosphine oxides, a new class of chiral ligands, in Ir(I)-catalyzed asymmetric imine hydrogenation
Xiao-bin Jiang,Adriaan J. Minnaard,B. Hessen,Bernard Feringa,A.L.L. Duchateau,J.G.O. Andrien,Jeroen A. F. Boogers,de Johannes Vries,A. L. L. Duschateau +8 more
TL;DR: Using pyridine as an additive allowed reduction of the L/Ir ratio to 1 without reduction of ee, and these new monodentate ligands were tested in the iridium-catalyzed hydrogenation of imines at 25 bar.

Asymmetric reductions with a chiral 1,4-dihydropyridine crown ether

Kinetic studies on the Rhizomucor miehei lipase catalyzed esterification reaction of oleic acid with 1-butanol in a biphasic system
TL;DR: In this paper, the kinetics of the esterification of oleic acid with 1-butanol catalyzed by free Rhizomucor miehei lipase in a biphasic system was studied in a batch reactor.
