摘要:The invention relates to a method for the synthesis of product molecules, wherein ultrashort laser pulses shaped with the aid of a pulse shaper are generated and a gas which contains educt molecules is fed onto a surface, on which the educt molecules are at least partially adsorbed, the shaped ultrashort laser pulses being directed onto the surface in order to control a reaction process for synthesis of the product molecules from educts adsorbed on the surface.

摘要:In this method, an oligonucleotide represented by formula (II) [wherein Y 1 , Q, Base, r and r′ are each as defined in claim 1 ] is prepared by using, as a synthesis unit, a novel nucleoside monomer compound represented by formula (I) [wherein X, R 1 , Y, Base, Z, Ar, R 2 , R 3 and n are each as defined in claim 1 ]. The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method can dispense with column-chromatographic purification in every reaction, and enables base elongation not only in the 3′-direction but also in the 5′-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.

摘要:A mono- or di-functional phosphoramidite phosphitylating agent is used to phosphitylate an ethylenically unsaturated alcohol. The product may be oxidised to form the corresponding phosphate ester which may be reacted in further steps to form phosphoryl choline derivatives. The process is of value in the synthesis of 2-(Methacryloyloxyethyl)-2'-(trimethylammoniumethyl)phosphate, inner salt. It has the advantage over prior art processes in that the starting materials and intermediates are more stable and consequently easier to handle.

摘要:The invention provides new reagents and processes for synthesizing oligonucleotides, including stereoselective oligonucleotide synthesis. In a first aspect, the invention provides novel monomer synthons for the synthesis of oligonucleotides. Monomer synthons according to this aspect of the invention are useful in the synthesis of oligonucleotides and can be used in place of the well known beta-cyanoethyl phosphoramidite monomer synthon in the phosphoramidite synthesis procedure. Certain monomer synthons according to this aspect of the invention are useful in this procedure for producing oligonucleotides having defined stereochemistry. In a second aspect, the invention provides processes for synthesizing monomer synthons according to the invention, including diastereomerically enriched or purified monomer synthons. In the processes according to this aspect of the invention, the chemical reactions are stereoretentive so that the products of each reaction retain the same stereoconfiguration as their precursor reagent. In a third aspect, the invention provides processes for synthesizing oligonucleotides using the well known phosphoramidite approach. In the processes according to this aspect of the invention, any of the monomer synthons according to the invention is used in place of the conventional beta-cyanoethyl phosphoramidite.
