                                    The absolute configuration of sec/prim- and prim/sec-1,2-amino alcohols is determined by comparison of the (1)H NMR chemical shifts of the auxiliary OMe or C alpha H groups at the corresponding bis-(R) and bis-(S)-MPA derivatives. This is the first NMR method that allows the assignment of absolute configuration without resorting to the shifts of hydrogens at the substrate and is based on the cross anisotropic interactions between auxiliaries.
