<p>Peptide derivs.(I; R1 = H, methyl, hydroxymethyl, mono-, di-or trihalomethyl; R2 = lower alkyl, hydroxy-(lower alkyl) or guanidino(lower alkyl), useful as bactericides, were prepared by the reaction of II(R10 = R1 or protected hydroxymethyl; R3, R4 = H or lower alkyl protecting group) and III(R5 = protected amino group; R20 = R2 or protected hydroxy-(lower alkyl) or guanidino-(lower alkyl) group.</p> |
