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

摘要:The invention relates to a novel strategy for the synthesis of Locked Nucleic Acid derivatives, such as α- L -oxy-LNA, amino-LNA, α- L -amino-LNA, thio-LNA, α- L -thio-LNA, seleno-LNA and methylene LNA, which provides scalable high yielding reactions utilising intermediates that also can produce other LNA analogues such as oxy-LNA. Also, the compounds of the formula X are important intermediates that may be reacted with varieties of nucleophiles leading to a wide variety of LNA analogues.
