The reduction of γ-N,N-dibenzylamino-β-ketophosphonates 4 derived from readily available (S)-tribenzylated amino acids was achieved with catecholborane at -20°C affording γ-amino-β-hydroxyphosphonates 5 in high diastereoselectivity and good chemical yield. These reactions provide a new entry to enantiomerically pure γ-amino-β-hydroxyphosphonates.
Stereoselective synthesis of β-amino alcohols: Diastereoselective reduction of chiral α-amino enones derived from amino acids

α-Amino acids are doubly benzylated at nitrogen to give N,N-dibenzyl amino acids, which can readily be converted to α'-amino enones 3. The α'-amino enones are very resistant to racemization, and undergo highly diastereoselective reduction to afford chiral amino alcohols upon treatment with L-Selectride under non-chelation control.

Remote asymmetric induction has been achieved in the conjugate addition of organocopper reagents to a novel 3-ketoacrylate system, 1. Conjugate additions proceed in moderate to good yield and with high regio-and stereoselectivity in the presence of diethylaluminum chloride. Copyright
