Abstract

Among the members of a family of diastereoisomeric pentopyranosyl‐(4′→2′)‐oligonucleotide systems derived from D‐ribose, D‐xylose, L‐lyxose, and L‐arabinose, the α‐arabinopyranosyl system shows by far the strongest Watson____Crick base pairing. The system is, in fact, one of the strongest oligonucleotide‐type base‐pairing systems known. It undergoes efficient cross‐pairing with all the other members of the pentopyranosyl family, but not with RNA and DNA. The paper describes the synthesis and pairing of the properties of α‐L‐arabinopyranosyl‐(4′→2′)‐oligonucleotides.

## Abstract Our studies of __α__‐L‐Threofuranosyl‐(3′→2′)‐oligonucleotides (‘TNA') are part of a systematic experimental inquiry into the base‐pairing properties of potentially natural nucleic acid alternatives taken from RNA's close structural neighborhood. TNA is an efficient __Watson‐Crick__ bas
