标 题 :Process for the synthesis of oligonucleotides
发明人：LEUCK MICHAEL; WOLTER ANDREAS; STUMPE ALFRED
权利人:LEUCK MICHAEL; WOLTER ANDREAS; STUMPE ALFRED; SIGMA ALDRICH CO LLC
摘要:The present invention discloses novel methods for the synthesis of oligonucleotides with nucleoside phosphoramidites on solid supports. The methods comprise the stepwise chain assembly of oligonucleotides on supports with 5′-acyl phosphoramidites. The synthesis cycles consist of a front end deprotection step which is conducted with a solution of a primary amine or a phenolate, a phosphoramidite coupling step with a 5′-acyl nucleoside phosphoramidite in the presence of an activator, a phosphite oxidation step and an optional capping step. The novel methods improve the quality of synthetic oligonucleotides due to the irreversibility of the front end deprotection step, which prevents the formation of deletion sequences, and due to the avoidance of acidic reagents in the synthesis cycles, which prevent the formation of depurination side products. The invention further discloses novel nucleoside phosphoramidite compositions wherein the phosphoramidites carry acyl front end protective groups which are cleavable with primary amines or phenolates. The invention is applicable to the synthesis of oligodeoxyribonucleotides, oligoribonucleotides and oligonucleotides with modifications in their sugar or phosphate groups.

摘要:This disclosure refers to a method for the synthesis of polymers with weight average molecular weights greater than 50,000 g/mol, chemically inert, with a minimum decomposition temperature of 425° C., and a main chain composed only of carbon-carbon bonds, which contain structures of the type of naphthalene, phenanthrene, anthracene, pyrene, carbazole or any other where two or more aromatic rings of six carbon atoms of the benzene-type are fused, which may or may not contain aromatic heterocycles. In addition, the polymers obtained from the present disclosure may or may not contain fluorine atoms in their structure. The synthesis described here is carried out by means of polycondensation between a polycyclic aromatic compound and a compound with a carbonyl group in its structure in a strong acid medium.

摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.

标 题 :Synthesis of [2.2.1]bicyclo nucleosides

摘要:A synthesis of [2.2.1]bicyclo nucleosides which is shorter and provides higher overall yields proceeds via the key intermediate of the general formula III, wherein R4 and R5 are, for instance, sulfonates and R7 is, for instance, a halogen or an acetate. From compounds of the general formula II, such as 3-O-aryl-4-C-hydroxymethyl-1,2-O-isopropylidene-alpha-D-ribofuranose, intermediates of the general formula III are suitable for coupling with silylated nucleobases. Upon one-pot base-induced ring-closure and desulfonation of the formed [2.2.1]bicyclo nucleoside, a short route to each the LNA (Locked Nucleic Acid) derivatives of adenosine, cytosine, uridine, thymidine and guanidine is demonstrated. The use of the 5'-sulfonated ring-closed intermediate also allows for synthesis of 5'-amino- and thio-LNAs.
