A linear relationship between electronegativity of 2′-substituents and conformation of adenine nucleosides
Abstract From the 1 H NMR studies of various 2′-substituted 2′-deoxyadenosines, a relationship between electronegativity of substituents and conformation of the sugar moiety was elucidated.

Studies of Nucleosides and Nucleotides. XXXVIII. Synthesis of 8-Bromoadenosine Nucleotides
Direct bromination of adenine nucleotides was achieved by the use of bromine-water as brominating agent in the alkaline or buffer solution. By this method 8-bromoadenosine 2-', 3'-andExpand

Studies on the structure and stabilizing factor of the CUUCGG hairpin RNA using chemically synthesized oligonucleotides
A tridecaribonucleotide, r-UGAGCUUCGGCUC, and two analogues r(UGAGC)d(UUCG)r(GCUC) and r-TGAGCTTCGGCTC, which form a hairpin structure with a four-base-paired stem and a UUCG loop, were synthesized by the solid-phase phosphoramidite method. Expand
