  Synthesis of the Phosphoramidite Derivatives of 2‘-Deoxy-2‘-C-α-methylcytidine and 2‘-Deoxy-2‘-C-α-hydroxymethylcytidine:  Analogues for Chemical Dissection of RNA's 2‘-Hydroxyl Group

  摘要：

  Oligonucleotides containing 2'-C-alpha-methyl and 2'-C-alpha-hydroxymethyl modifications enable strategies for delineation of the distinctive role fulfilled by the 2'-hydroxyl group in RNA structure and function. Synthetic routes to the phosphoramidite derivatives of 2'-deoxy-2'-C-alpha-methylcytidine (14%, 15 steps) and 2'-deoxy-2'-C-alpha-hydroxymethylcytidine (19%, 10 steps) from methyl 3,5-di-O-(4-chlorobenzyl)-alpha-D-ribofuranoside are developed.
