标 题 :Synthesis of [2.2.1]bicyclo nucleosides
发明人：KOCHKINE ALEXEI; FENSHOLDT JEF; PFUNDHELLER HENRIK M
权利人:EXIQON AS
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.

标 题:Synthesis of purine locked nucleic acid analogues

权利人:SANTARIS PHARMA AS
摘要:The present invention relates to a new method for the synthesis of purine LNA (Locked Nucleic Acid) analogues which provides a higher overall yield. The method comprising a regioselective 9-N purine glycosylation reaction followed by a one-pot nucleophilic aromatic substitution reaction of the 6-substituent in the purine ring and simultaneous nucleophile-induced intramolecular ring closure of the C-branched carbohydrate to form novel purine LNA analogues. The novel strategy is illustrated by the synthesis of the novel compound (1S,3R,4R,7S)-7-benzyloxy-1-methanesulfonylmethyl-3-(guanin-9-yl)-2,5-dioxabicyclo[2.2.1]heptane which is easily converted into (1S,3R,4R,7S)-7-hydroxy-1-hydroxymethyl-3-((2-N-isobutyrylguanin-9-yl)-2,5-dioxabicyclo[2.2.1]heptane after isobutyryl protection of the 2-amino purine group and subsequent substitution of 1-methanesulfonyl with benzoate, debenzoylation and debenzylation.
