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.

标题 :Reagents and process for synthesis of oligonucleotides containing phosphorodithioate internucleoside linkages
发明人：IYER RADHAKRISHNAN P
权利人:HYBRIDON INC
摘要:The invention provides new methods for synthesizing oligonucleotides containing at least one, and preferably all phosphorodithioate internucleoside linkages with less than 5% phosphoromonothioate contamination. This level of purity in the synthesis of phosphorodithoates has previously been very difficult to achieve with all existing methods. The invention further provides phosphorothioamidite nucleoside synthons comprising a sulfur protecting group that is stable under normal oligonucleotide synthesis conditions.
