  A new approach for the synthesis of 3′-deoxy-3′-C-formyl-ribonucleosides and the synthesis of alternating methylene(methylimino) linked phosphodiester backbone oligonucleotides with 2′-OH and 2′-OMe groups

  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.
