Although enamines are known to be excellent addends in many Michael type reactions, the reaction of enamines with Schiff bases has hitherto never been found in the literatures. We now would like to report the reaction and its stereochemical consequence. Reaction of 1-morpholino-l-cyclohexene (Ia) o

## Abstract This short review concerns the protonation of Schiff bases by halogenic or carboxylic acids with a bias toward the chromophore of visual and bacterial rhodopsins. It is pointed out that the weak acids available in these pigments could not protonate the retinyl Schiff base 100% and that

The pyridoxal Schiff bases of the polypeptides poly(L-lysine), poly(L-ornithine), and poly(L-a,y-diaminobutyric acid) were prepared and investigated in water/methanol by CD spectra and equilibrium dialysis experiments. Only the poly(L-a,?-diaminobutyric acid) derivative is characterized by a relevan
