New oligonucleotide analogues based on morpholine subunits joined by oxalyl diamide tether
摘要:
We report on the design, synthesis and some of the properties of the new oligonucleotide analogues based on morpholine nucleoside (MorB) subunits joined by an oxalyl diamide tether instead of a phosphate group. The synthetic strategy and oligomer design are optimized to easily obtain target substances without using protective groups. The dimers HOMorU-Ox-NHMorU, HOMorU-Ox-NHMorA, and uracil containing the hexamer HOMorU-(Ox-NHMorU)(5) were synthesized. The structures of all substances were confirmed by H-1, C-13, NMR, and mass spectroscopy. Base stacking interactions in dimers were revealed by CD-spectra data. (C) 2007 Elsevier Inc.
