  1-[5-O-acetyl-2-deoxy-3-O-(4,4'-dimethoxytrityl)-α-D-pentofuranosyl]-5-methyl-4-(4-phenoxyphenylamino)pyrimidin-2(1H)-one 在 sodium methylate 、 N,N-二异丙基乙胺 作用下， 以 甲醇 、 二氯甲烷 为溶剂， 反应 2.5h， 生成 Diisopropyl-phosphoramidous acid (2R,3S,5S)-2-[bis-(4-methoxy-phenyl)-phenyl-methoxymethyl]-5-[5-methyl-2-oxo-4-(3-phenoxy-phenylamino)-2H-pyrimidin-1-yl]-tetrahydro-furan-3-yl ester 2-cyano-ethyl ester

  Stabilizing a DNA Three-Way Junction by Insertion of N4-Aryl-2-deoxy-5-methylcytidines.

  摘要：

  4,4'-Dimethoxytrityl and acetyl sugar protected alpha and beta thymidines are converted into the corresponding N-4-aryl-2-deoxy-5-methylcytidines via 4-(2,4,6-trimethylbenzenesulfonyloxy) pyrimidin-2(1H)-one nucleosides. These compounds were used for DNA synthesis after deacetylation and phosphitylation. Increased melting temperatures (6.2-9.6 degrees C) of three-way junctions (TWJ) were observed when N-4-(2-anilinophenyl)-, N-4-(2-benzylphenyl)- or N-4-(2-fluorenyl)-2-deoxy-5-methylcytidines were inserted into the middle of the junction region. A 26.6 degrees C increase in melting temperature was observed using a nucleosides in one of the strands of TWJ and with insertion of 2-deoxy-N-4-(2-fluorenyl)-5-methyl-alpha-cytidine at the junction. A large increase in thermal melting (18.8 degrees C) of the TWJ was also observed when 2-deoxy-5-methyl-N-4-(4-phenoxyphenyl)-alpha-cytidine was inserted at the junction as a chimeric nucleoside into a strand of beta nucleosides.
