Abstract
A novel ligand having the Formula 1 structure has proved remarkably successful in the amination of butadiene monoepoxide, which is a potentially desirable substrate for an asymmetric synthesis providing access to each enantiomer of vinylglycinol. ##STR1## This and other ligands described are useful for chiral induction of bond forming reactions with an epoxide substrate.
