Abstract

Abstract By reacting p-nitrophenyl esters of L-α-amino acids with α-(3-aminopropyl)-ω- (aminomethyl)-poly (oxyethylene), diamides having the structure [X-NHCH (R) CONH] 2 M x'were prepared, X being the protective group Boc or Z, R being residues of glutamic and aspartic acid, phenylalanine and tyrosine, and M x'being the poly (oxyethylene) chain with the (-CH 2) 3-and-CH 2-endgroups. The diamides were characterized by IR and 1 H NMR ...
