Syntheses of four N-Fmoc δ-amino acids with an ether linkage in the main chain and four different nucleobases on the side chain, Fmoc-NH- C*H(CH2-CH2-B)-CH2-O-CH2-COOH (B=thymine, uracil, N4-benzoylcytosine, and N2-isobutyrylguanine) are described. The δ-amino acids were prepared through 8-12 step synthesis starting from L-homoserine and could be linked together to form novel peptide nucleic acids (oxy-PNAs = OPNAs).
