Abstract:(N,N-Dimethylamino)phosphoryl chloride morpholinonucleoside monomers were synthesized through protection of amine group in base, protection of 5'-hydroxyl , transformation of ribose to morpholine ring, N-trityl in morpholine ring, deprotection of hydroxyl group and phosphorylation of hydroxyl group using cytidine and ribothymidine as raw material respectively. The total yield were 20% and 30%, respectively. All intermediates and the target products were characterized by LC-MS, 1H NMR, 31P NMR, and their purity were measured by HPLC. The influence of amino and hydroxyl protective reagents and the ratio of substances on the yield of monomer 7a was also investigated.
Key words:phosphoramide morpholino oligonucleotide; monomer; synthesis
