标 题 :Synthesis of stable quinone and photoreactive ketone phosphoramidite reagents for solid phase synthesis of photoreactive-oligomer conjugates
发明人：FENSHOLDT JEF
权利人:EXIQON AS
摘要:Quinone phosphoramidite reagents as well as photoreactive ketone phosphoramidite reagents, such as anthraquinone phosphoramidite reagents and benzophenone phosphoramidite reagents were synthesized and used for the solid phase synthesis of photoreactive-oligonucleotide conjugates. These phosphoramidite reagents are stable, suitable for large-scale synthesis and designed for automated solid phase synthesis of oligomers terminating in a photoreactive moiety.

标题 :Non-nucleoside linkers for convenient attachment of labels to oligonucleotides using standard synthetic methods

摘要:Pseudonucleosides and pseudonucleotides are useful in the synthesis of oligomers which contain these components as a means to derivatize the resulting oligonucleotide to useful substituents such as chelators, intercalators, or lipophilic compounds. In general, these pseudonucleotide components are of the formula: (1) wherein each Y is independently O or S; each X is independently H, PO3-2, an activated nucleotide synthesis coupling moiety, a protecting group, a nucleoside, a nucleotide or a nucleotide sequence, or comprises a solid support; F is a functional group capable of linking an additional moiety or said group already reacted to effect the binding of said additional moiety; &squ& is an organic backbone which does not contain additional F or Y-X substituents and which is either achiral even when the Y-X substituents are different, or is a single enantiomer of a chiral compound; with the proviso that at least one X is a nucleoside, nucleotide, nucleotide sequence, an activated nucleotide synthesis coupling moiety, or comprises a solid support, or F represents said functional group already reacted with an additional group. Oligonucleotides having the pseudonucleoside at the 3' terminus are particularly stable in vivo.

摘要:The subject invention provides catalytical compounds/complexes, compositions comprising such compound/complex, synthesis of the compounds/complexes, and methods of using such compounds/complexes as catalysts in, for example, carbon isotope exchange (CIE) on target bioactive molecules. Methods that allow CIE directly on drug candidates are of great importance to chemistry, biology, and medicine. Especially valuable are catalytic procedures that rely on a limited collection of available labeled materials. The instant method comprises converting a methyl group to terminal â•?CH2 utilizing transfer dehydrogenation catalysts to enable V-based olefin metathesis, followed by a hydrogenation step. The one-pot strategy allows the formal methylation/demethylation sequence and can be applied to an assortment of alkyl-containing compounds.

摘要:Described herein is a process of producing α,β unsaturated acids and amides and their intermediates via a photocatalytic reaction in the presence of a photocatalyst, oxygen, and optionally a solvent. The photocatalyst contains a tungstic acid or a salt of a tungstic acid. The process is simple, clean, and energy efficient, and provides good conversion, good selectivity, good turnover, and easy purification of end products.
