The synthesis of deuterionucleosides

Abstract

Abstract: The synthesis of deuterionucleosides for site-specific incorporation into oligo-DNA or-RNA is herein reviewed for NMR or biological studies. The review covers the following aspects: (i) deuteration of the aglycone; (ii) single-site chemical deuteration of the sugar residues; (iii) multiple-site chemical deuteration of the sugar residues; (iv) enzymatic synthesis of deuterated nucleosides or nucleotides; and (v) synthesis of labelled nucleosides with multiple isotopes
