  摘要：

  A stereoselective synthesis of 3'-deoxy-3'-C-formyl-5-methyluridine 2 is described via the dithiane 4 as the key intermediate. Compound 2 was coupled with 3 into a novel ribo-MMI dimer 1. The dimer was then incorporated into antisense oligonucleotides which were found to have high binding affinity to the target RNA. (C) 2000 Elsevier Science Ltd. All rights reserved.

  Synthesis of a novel ribo-MMI dimer with 2'-OH and 2'-OMe in 5'- and 3'-nucleosides, respectively is presented. The synthesis was accomplished by reductive coupling of 3'-deoxy-3'-C-formyluridine and 2'-O-methyl-5'-O-methylaminouridine via a thioacetal as the key intermediate for the top part of the dimer. Incorporation of ribo-MMI dimers into oligonucleotides increased binding affinity for target RNA.
