, p. 3969 - 3972 (2005)
The carboranyl cage is a new modifying entity for nucleosides, DNA oligonucleotides, and other biomolecules. Herein, the first reliable method for the synthesis of nucleosides modified with a carborane cluster at the 2′-position is described.

We previously reported that reducing-environment-responsive prodrug-type small interfering RNA (siRNA) bearing 2′-O-methyldithiomethyl (2′-O-MDTM) uridine exhibits efficient knockdown activity and nuclease resistance. In this report, we describe the prepa

A rapid and effective method of an automatic oligoribonucleotide synthesis alternative to the phosphoramidite one was developed. This method is based on the phosphotriester approach to internucleotide bond formation under intramolecular O-nucleophilic cat

The azidomethyl and 2-(azidomethyl)benzoyl as 2'-OH protecting groups are reported for preparation of oligoribonucleotides by the phosphotriester solid-phase method using O-nucleophilic intramolecular catalysis. The procedures for the synthesis of the corresponding monomer synthons were developed and the usefulness of the application of 2'-O-azidomethyl and 2'-O-2-(azidomethyl) benzoyl groups was examined in the synthesis of different RNA fragments with a chain length of 15-22 nucleotides. The azidomethyl group was found to be more preferable for effective synthesis of oligoribonucleotides. Hybridization properties of RNAs toward their complementary oligonucleotides were examined before and after the removal of 2'-O-azidomethyl groups.
The 4-(N-dichloroacetyl-N-methylamino)benzyloxymethyl group for 2′-hydroxyl protection of ribonucleosides in the solid-phase synthesis of oligoribonucleotides
Cieslak, Jacek,Grajkowski, Andrzej,Kauffman, Jon S.,Duff, Robert J.,Beaucage, Serge L.
, p. 2774 - 2783 (2008/09/20)
(Chemical Equation Presented) Emerging RNA-based technologies for controlling gene expression have triggered a high demand for synthetic oligoribonucleotides and have motivated the development of ribonucleoside phosphoramidites that would exhibit coupling
Assessment of 4-nitrogenated benzyloxymethyl groups for 2′-Hydroxyl protection in solid-phase RNA synthesis
Cieslak, Jacek,Kauffman, Jon S.,Kolodziejski, Michelle J.,Lloyd, John R.,Beaucage, Serge L.
, p. 671 - 674 (2008/02/05)
The search for a 2′-OH protecting group that would impart ribonucleoside phosphoramidites with coupling kinetics and coupling efficiencies comparable to those of deoxyribonucleoside phosphoramidites led to an assessment of 2′-0-(4-nitrogenated benzyloxy)m
Synthesis of RNA using 2′-O-DTM protection
Semenyuk, Andrey,Foeldesi, Andras,Johansson, Tommy,Estmer-Nilsson, Camilla,Blomgren, Peter,Braennvall, Mathias,Kirsebom, Leif A.,Kwiatkowski, Marek

tert-Butyldithiomethyl (DTM), a novel hydroxyl protecting group, cleavable under reductive conditions, was developed and applied for the protection of 2′-OH during solid-phase RNA synthesis. This function is compatible with all standard protecting groups used in oligonucleotide synthesis, and allows for fast and high-yield synthesis of RNA. Oligonucleotides containing the 2′-O-DTM groups can be easily deprotected under the mildest possible aqueous and homogeneous conditions. The preserved 5′-O-DMTr function can be used for high-throughput cartridge RNA purification. Copyright

Pechenov,Zavgorodny,Shvets,Miroshnikov
, p. 327 - 333 (2007/10/03)
Ribonucleoside 2′- and 5′-O-methylthiomethyl derivatives were synthesized from selectively protected nucleosides by the action of a dimethyl sulfoxide-acetic anhydride-acetic acid mixture.
