Abstract
The polymerization rate of N-carboxy dehydroalanine anhydride (I) was compared with that of N-carboxy DL-alanine anhydride, and it was found, that the former was much slower than the latter at 30°C. Polydehydroalanine (IV) was obtained by heating the substance I in dry pyridine at 100°C, or by adding a small amount of triethylamine into the boiling toluene solution of I. The substance IV was water-soluble brown powder, the actual structure of which was supposed to be a pyrolidone-type polypeptide VI containing about 10% of dehydroalanyl residues.Keywords
