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)
Fmoc-NH-C * H(CH 2 -CH 2 -B)-CH 2 -O-CH合成四个在主链上带有醚键且在侧链上具有四个不同核碱基的N -Fmocδ-氨基酸描述了2- COOH(B =胸腺嘧啶,尿嘧啶,N 4-苯甲酰基胞嘧啶和N 2-异丁酰基鸟嘌呤)。δ-氨基酸是通过从1-高丝氨酸开始的8–12步合成制备的,可以连接在一起形成新的肽核酸(氧基-PNAs = OPNAs)。
