E. Rozners et R. Stromberg, SYNTHESIS AND PROPERTIES OF OLIGORIBONUCLEOTIDE ANALOGS HAVING AMIDE (3'-CH2-CO-NH-5') INTERNUCLEOSIDE LINKAGES, Nucleosides & nucleotides, 16(7-9), 1997, pp. 967-970
Amide linked ribonucleoside dimer 5 was prepared and converted into se
lectively protected H-phosphonate building block 9. Oligoribonucleotid
e duplexes having amide linkages at selected sites were synthesized an
d their stability was studied by UV melting experiments.
