Abstract

L-Ornithine derivatives of thymine, and thymidine gave oligomers by solid phase elongation reactions. These oligomers 2 and 3, however, hardly interact with the complementary polynucleotide. Conformational studies of the oligomers with CD and NMR revealed that stable intramolecular hydrogen bonding was formed between thymine base and ornithine unit.

This paper is dedicated to the late Professor Tsujiaki Hata, an extraordinary chemist.
