Structure-stability correlations for imine formation in aqueous solution

Imine formation between 25 aldehydes and 13 amines in aqueous solution in the pH range 7-11 was studied by 1H NMR spectroscopy. A three-parameter linear equation correlating logarithms of imine formation constants with pKa and HOMO energies of amines and LUMO energies of aldehydes is proposed. In view of the widespread occurrence of imine-forming processes in both chemistry and biology, the data presented are of significance for physical organic chemistry and of particular interest for dynamic combinatorial chemistry.

Certain derivatives of particular 3-thiolated cephalosporins

Compounds of the formula STR1 wherein A is hydrogen, hydroxy, methyl or methoxy, R1 is hydrogen, sodium or potassium, R2 is carboxyl or an aliphatic, aromatic or heterocyclic radical to which there is also attached a strongly acidic group in the form of its sodium or potassium salt, and R3 is 1,2,3-triazol-5-yl, such group being unsubstituted or substituted with one or two lower alkyl groups of one to four carbon atoms are prepared by reacting the appropriate aldehyde with the corresponding amphoteric cephalosporin.
