A series of 1-(3-alkyl-2,3-dideoxy-alpha,beta-D-erythro-pentofuranosyl)thymines (3'-alkyl-3'-deoxythymidines) has been prepared from 5-O-(tert-butyldiphenylsilyl)-2,3-dideoxy-D-glycero-pent-2- enono-1,4-lactone ((S)-5-[(tert-butyldiphenylsilyl)oxymethyl]-2(5H)- furanone) by Michael addition of the appropriate organocopper reagent, followed by reduction of the lactone, acetylation of the resulting hemiacetal
The present invention provides a novel modified oligonucleotide monomer useful in molecular biological techniques such as capture and/or detection of nucleic acids, amplification of nucleic acids and sequencing of nucleic acids. The modified oligonucleotide monomer comprises an intercalator that can intercalate into an antiparallel duplex from the major groove.
The disclosure provides multimeric oligonucleotide compounds, comprising two or more target-specific oligonucleotides (e.g., antisense oligonucleotides (ASOs)), each being resistant to cleavage, and linked together by a cleavable linker. In particular, two or more linked target-specific oligonucleotides, each to a different target, allows concomitant inhibition of multiple genes' expression levels, while exhibiting favorable pharmacokinetic and pharmacodynamic properties. Methods of making and uses of the described compounds are also provided

The synthesis of some 3'-deoxy-3'-C-methylnucleoside analogues bearing naturally occuring nucleic acid bases was achieved from the preparation of a suitable peracylated 3-deoxy-3-C-methyl sugar using a stereoselective pathway. In addition, examples of chemical modifications at the 2' position are presented.
