  A Facile Synthesis of the Phosphoramidites of 2-N-Methyl-2′-deoxy (or 2′-O-allyl)-ψ-isocytidine, 1, 3-Dimethyl-2′-deoxy-ψ-uridine andN1-Methyl-2′-O-allyl-ψ-uridine as Synthons Suitable for Oligonucleotide Synthesis

  摘要：

  An efficient and facile syntheses of 5'-O-(4,4'-dimethoxytrityl)-3'-[2-cyanoethyl bis(1-methylethyl)]phosphoramidites of 2-N-methyl-2'-deoxy-psi-isocytidine (h), 2-N-methyl-2'-deoxy-alpha-psi-isocytidine (13 ), 2-N-methyl-2'-O-allyl-psi-isocytidine (11), 1,3-dimethyl-2'-deoxy-psi-uridine (4) and N1-methyl-2'-O-allyl-psi-uridine (19) have been accomplished in good overall yields. The pyrimidine-pyrimidine transformation reaction was found to be useful for the preparation of 2-N-methyl-2'-O-allyl-psi-isocytidine (10). The utility of these novel phosphoramidites is demonstrated by their incorporation into oligonucleotides via solid-support, oligonucleotide methodology.
