Ð-Chiral monodentate diamidophosphites as ligands for Rh-catalyzed asymmetric reactions
S. E. Lyubimov, V. A. Davankov, P. V. Petrovskii, and N. M. Loim
A series of P-chiral monodentate diamidophosphite ligands of the 1,3-diaza-2-phosphabicyclo[3.3.0]octane family was tested in the Rh-catalyzed hydrogenation of dimethyl itaconate and addition of phenylboronic acid at the carbonyl group of trans-cinnamaldehyde. The enantioselectivities and conversions of these reactions are strongly dependent on the nature of the exo-cyclic substituent of the ligand.
