Abstract
In the reactions of 3-amino-1,2-propanediol with aromatic aldehydes, f ive-component ring-chain tautomeric mixtures were formed, involving ox azolidine and oxazine C-2 epimers and the corresponding Schiff base. T hese multicomponent tautomeric equilibria could be described by the eq uation log K = rho sigma(+) + K-0, used earlier for the two- and three -component equilibria relating to only oxazine or oxazolidine rings.
