A C(aryl)N(amine) bond atropisomeric aminophosphine: preparation and use as a ligand in a catalytic asymmetric allylic alkylation
摘要:
The existence of 3 as a pair of stable atropisomers has been demonstrated analytically through chiral phase LC-CD investigations. Resolution of 3d was achieved by preparative chiral HPLC. Finally, the ability of the first C(aryl)-N(amine) axially chiral phosphine ligand 3d is demonstrated in a catalytic asymmetric reaction. (C) 2003 Elsevier Ltd. All rights reserved.
