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.

发明人：ENDO ATSUSHI
权利人:MODERNA TX INC
摘要:Provided herein are methods of making trinucleotides and tetranucleotides for use as 5′ mRNA caps. The methods utilize a novel “top-downâ€? strategy and provide for synthesis of oligonucleotides with higher yields and increased efficiency compared to traditional methods. A key step of the methods disclosed, herein can also be adapted to utilize a “one-potâ€? approach, resulting in an increase in the yield of the final oligonucleotide product.
