Abstract

In the reactions of (1R*,2S*)- or (1S,2S)-2-amino-1-phenyl-1,3-propanediol with aromatic aldehydes, five-component ring-chain tautomeric mixtures were formed, involving C-2 epimers of structurally isomeric oxazolidines and the corresponding Schiff bases. These multicomponent tautomeric equilibria could be described by the equation log K-X = rho sigma(+) + log K-X=H.(23).
