Salicylidenamino chirality rule

Of the number of chromophoric derivatives of chiral amines for potential use in the establishment of their absolute configuration by BCD measurement only a few have proven to be generally useful. Of these, intensive investigation of the Af-salicylidene (Schiff base) derivatives of chiral primary amines, including unsubstituted and ring-substituted a- and S-arylalkylamines, a-amino acids, unsaturated and satnrated aliphatic and alicyclic amines, and amino sugars, has resulted in the formulation of the salicylidenamino chirality rule ° °. The application of this rule has recently been reviewed and has been successfully used for the establishment of absolute configuration of chiral primary amines in connection with other stereochemical studies. In related studies, the conformations of a series of pyridoxyl-L-a-amino acid Schiff bases were deduced from their CD spectra ...
