Synthesis and polymerization of nucleic acid base substituted L-lysine

Summary

Poly-l-lysines containing nucleic acid bases, that is, adenine, thymine, uracil and theophylline were synthesized. The nucleic acid base substituted l-lysine derivatives were prepared from α,N-Cbz-l-lysine and the p-nitrophenyl esters of the carboxyethyl derivatives of the nucleic acid bases. The polymers were obtained from these l-lysine derivatives by the NCA method.
