Abstract
New chiral amidophosphites were synthesized and tested in the Ir-catalyzed hydrogenation of 4-substituted 1,3-dihydro-2H-1,5-benzodiazepin-2-ones and Rh-catalyzed hydrogenation of dehydro amino acid derivatives. The triphenylphosphine additive can considerably increase the enantioselectivity of both processes.
