The preparation of a new class of backbone-modified PNA mimetic incorporating thymine is described. Target dipeptoid monomer 21 was synthesised from an N-[2-(thymin-1-yl)ethyl]glycinate ester and a properly protected iminodiacetic acid. The distinctive structural motif in the backbone is acarboxy group, inserted to impart water solubility to the oligomer. Two achiral oligopeptoid sequences (8-mer and
