NMR determinations of the absolute configuration of alpha-chiral primary amines.

We have established a methodology to determine the absolute configuration of alpha-chiral primary amines by derivatization to the corresponding imines with each enantiomer of 2'-methoxy-1,1'-binaphthalene-8-carbaldehyde (1). This methodology proceeds on the basis of modified Mosher's method, and sufficiently large Deltadelta(R)(S) values can be obtained to elucidate the stereochemistry of the amines.
