  Preparation of 2'-O-(.beta.-Cyanoethyl phosphoramidites) of 3'-Deoxycytidine and 3'-Deoxyguanosine and Their Use for Solid-Phase Synthesis of Oligodeoxynucleotides Containing 2',5'-Phosphodiester Linkages

  摘要：

  Convenient, preparative scale synthetic routes to 2'-O-(beta-cyanoethyl N,N-diisopropylphosphoramidites) of 3'-deoxycytidine (1) and 3'-deoxyguanosine (2) are described. The 3'-deoxycytidine nucleoside 5 was constructed by a modified Hilbert-Johnson reaction in which N-(4-isobutyryl)-cytosine (4) was ribosylated with anomeric acetate 3. Nucleoside 5 was converted to 5'-O(dimethoxytrityl)-4-N-isobutyryl-3'-deoxycytidine (7) and phosphitylated to provide phosphoramidite 1. Access to derivatives of 3'-deoxyguanosine was provided by selective removal of the 3'-hydroxyl of guanosine (10). Thus, the 3'-O-thiocarbamate of 5'-O-(dimethoxytrityl)-2-N-(dimethylformamidyl)- 2'-O-(triisopropylsilyl)guanosine (12) was reduced with tributyltin hydride and converted to phosphoramidite 2. In results to be reported elsewhere, phosphoramidites 1 and 2 were used to prepare oligodeoxynucleotides containing novel 2',5'-phosphodiester linkages using automated solid-phase DNA synthesis methods with average stepwise coupling yields of >97%.

• Some observations relating to the use of 1-aryl-4-alkoxypiperidin-4-yl groups for the protection of the 2′-hydroxy functions in the chemical synthesis of oligoribonucleotides
  作者：Wayne Lloyd、Colin B. Reese、Quanlai Song、Anthony M. Vandersteen、Cristina Visintin、Pei-Zhou Zhang

  DOI：10.1039/a908149f

  日期：——

  The comparative rates of acid-catalysed removal of ten 1-aryl-4-methoxypiperidin-4-yl 8 (R = Me) [including the previously reported Ctmp 5 and Fpmp 6] protecting groups for the 2′-hydroxy functions in oligoribonucleotide synthesis are discussed. These studies have led to the development of the 1-(4-chlorophenyl)-4-ethoxypiperidin-4-yl (Cpep) protecting group 8 (R = Et, R1 = R2 = H, R3 = Cl) which is both more stable than the Ctmp and Fpmp groups at pH 0.5 and more labile at pH 3.75. The influence of the ribonucleoside aglycone on the stability of the 2′-O-Fpmp and 2′-O-Ctmp protecting groups both at low and high pH is examined.

  讨论了在寡核苷酸合成中，十个1-芳基-4-甲氧基哌啶-4-基（R = Me，包括先前报道的Ctmp 5和Fpmp 6）保护基对2'-羟基功能的酸催化去除的相对速率。这些研究导致开发了1-(4-氯苯基)-4-乙氧基哌啶-4-基（Cpep）保护基8（R = Et，R1 = R2 = H，R3 = Cl），其在pH 0.5下比Ctmp和Fpmp群更加稳定，而在pH 3.75下更加不稳定。研究了核苷酸基在低pH和高pH下对2'-O-Fpmp和2'-O-Ctmp保护基稳定性的影响。

  [reaction: see text] The solid-phase synthesis of oligoribonucleotides derived from ribonucleosides esterified at the 2'- (or 3'-) position with the levulinyl (Lv) group is described. The oligomers can be released from the solid support as 2'-O-Lv ester derivatives or fully deprotected while still attached to the solid support.
