Synthesis of partially-deuterated 2′-deoxyribonucleoside blocks and their incorporation into an oligo-DNA for simplification of overcrowding and selective enhancement of resolution and sensitivity in the 1H-NMR spectra
摘要:
The chemical synthesis of appropriately protected partially-deuterated 2'((R) under bar/(S) under bar), 3',5'((R) under bar/(S) under bar)-H-2(3)-2'-deoxyribonucleoside blocks [similar to 43 atom % H-2 at C5'((R) under bar), similar to 57 atom % H-2 at C5'((S) under bar); similar to 15 atom % H-2 at C2'((R) under bar, similar to 85 atom % H-2 at C2'((S) under bar) and >99 atom % H-2 at C3'] is reported. The availability of these deuterium labelled blocks on large scale has enabled the chemical assemblage of the deuterio isotopomeric 12 mer [d((C) double under bar(1)(G) double under bar(2)(C) double under bar(3)(G) double under bar(4)(A) double under bar(5)(A) double under bar(6)(T) double under bar(7)(T) double under bar(8)(C) double under bar(9)(G) double under bar(10)(C) double under bar(11)(G) double under bar(12))](2) DNA duplex by standard solid-phase synthesis protocol in order to demonstrate the usefulness of the new "NMR-window III" approach (see the following paper).
