Conformationally locked nucleosides. Synthesis and stereochemical assignments of 2′-C,4′-C-bridged bicyclonucleosides
摘要:
1-alpha-O-Methyl-3-O,5-O-TIPDS-arabinose was converted, in multiple steps, to 2,6-dioxabicyclo[3,2,1]octane derivatives, which were condensed with silylated nucleoside bases to give the desired 2',4'-bridged bicyclonucleosides. In this article, synthesis and stereochemical assignments of the bicyclonucleosides are described. (C) 1999 Elsevier Science Ltd. All rights reserved.

A conformationally locked, 2',4'-C-bridged 2'-deoxyribofuranoside2 was condensed with silylated pyrimidines to give 2',4'-C-bridged bicyclonucleosides, which were converted to the phosphoramidites and incorporated into oligodeoxynucleotides (ODNs). The hybridization data of the modified ODNs to DNA and RNA are presented.
