The (3′→2′)‐phosphodiester glyceric acid backbone containing an acyclic oligomertagged with 2,4‐disubstituted pyrimidines as alternative recognitionelements have been synthesized. Strong cross‐pairing of a 2,4‐dioxo‐5‐aminopyrimidine hexamer, rivaling locked nucleic acid (LNA) and peptide nucleic acid (PNA), with complementary adenine‐containing DNA and RNA sequences was observed. The corresponding
