Synthesis of functionalised nucleosides for incorporation into nucleic acid-based serine protease mimics
Catry, Mieke A.,Madder, Annemieke
, p. 114 - 129 (2007)
The synthesis of nucleosides modified with an extra imidazole, carboxyl and hydroxyl group is described. These nucleosides can be incorporated into an oligonucleotide duplex, thus generating a novel type of serine protease mimic.

A series of triphenylphosphinecarboxamide (TPPc) derivatives were designed and synthesized as alternative reagents to triphenylphosphine for the facile reduction of azides. The TPPc derivatives performed as efficient reducing agents for the synthesis of primary amines without the need for an additional hydrolysis procedure. The TPPc derivatives were also applied to nucleic acid sensing using a RhAz-oligonucleotide conjugate in a DNA-templated fluorogenic reaction.
Monomers for oligonucleotide synthesis with linkers carrying reactive residues: II. The synthesis of phosphoamidites on the basis of uridine and cytosine and containing a linker with methoxyoxalamide groups in position 2′

, p. 234 - 242 (2007/10/03)
A convenient preparative synthesis of 2′-amino-2′-deoxyuridine was developed. Starting from 2′-amino-2′-deoxyuridine and 2′-amino-2′-deoxycytidine, monomers for the phosphoamidite oligonucleotide synthesis were obtained that carry a linker with methoxyoxalamide groups in position 2′.
Efficient synthesis of 2′,3′-dideoxy-2′-amino-3′- thiouridine
Dai, Qing,Piccirilli, Joseph A.
, p. 2169 - 2172 (2007/10/03)
Metal ion rescue experiments provide a powerful approach to establish the presence and role of divalent metal ions in the biological function of RNA. The utility of this approach depends on the availability of suitable nucleoside analogues. To expand the
Method of preparation of known and novel 2'-modified nucleosides by intramolecular nucleophilic displacement
-
, (2008/06/13)
A method for the preparation of 2'-modified nucleosides is provided. The method comprises a novel intramolecular nucleophilic displacement reaction. Included in the invention are novel 2'-modified pyrimidines and purines prepared according to the method of the invention, novel pyrimidines and purines bearing a 2',3' heterocyclic substituent and oligonucleotides containing said 2'-modified pyrimidines and purines. The 2'-modified nucleosides are useful as anti-viral and anti-neoplastic agents.
Synthesis of Phosphoramidite Building Blocks of 2′-Amino-2′-deoxyribonucleosides: New Compounds for Oligonucleotide Synthesis
Greiner, Beate,Pfleiderer, Wolfgang
, p. 1528 - 1544 (2007/10/03)
The chemical synthesis of 2′-amino-2′-deoxyribonucleosides of uracil, cytosine, adenine, and guanine, and their conversion into suitably protected 3′-phosphoramidite building blocks 35-40 for oligonucleotide synthesis are described. The aglycone and the 2′-amino functions were protected using the 2-(4-nitrophenyl)ethoxycarbonyl (npeoc) group. The synthesis of the 3′-?-succinyl (3′-?-(3-carboxypropanoyl))-substituted starting nucleoside 41 is described and its behavior examined in solution and on solid phase with regard to an anticipated migration during 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) deprotection. Oligonucleotides were prepared using the new building blocks, and their hybridization properties were studied by UV-melting techniques.
Synthesis of oligonucleotides containing 2'-azido-and 2'-amino-2'-deoxyuridine using phosphotriester chemistry
Polushin, Nikolai N.,Smirnov, Igor P.,Verentchikov, Anatoli N.,Coull, James M.
, p. 3227 - 3230 (2007/10/03)
The phosphotriester method of oligonucleotide synthesis is shown to be useful for assembly of oligomers containing multiple internal 2'-azido substituents. Subsequent reduction of the azido group(s) with trialkylphosphines provides 2'-amino substituted oligonucleotides.
Novel nucleosides via intramolecular functionalization of 2,2'-anhydrouridine derivatives
McGee,Sebesta,O'Rourke,Martinez,Jung,Pieken
, p. 1995 - 1998 (2007/10/03)
The generation of novel ribonucleoside analogues derived from 2,2'-anhydrouridines by a 3'-hydroxyl directed intramolecular nucleophilic substitution of the 2'-position is described. The methodology allows for the efficient, regio- and stereoselective elaboration of the 2'-position, often under exceptionally mild reaction conditions.
