Abstract:
The present invention provides a method for producing guanidine crosslinked artificial nucleic acid (abbreviated hereinafter as GuNA), and an intermediate compound for the production thereof. Specifically, the present invention provides a method for producing a compound represented by general formula I: (in the formula, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , m and ring A are as defined in the specification) or a salt thereof wherein a reducing agent is reacted with a compound represented by general formula II: (in the formula, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , m, and ring A′ are as defined in the specification).

Claim (Index 25):
A method for preparing a compound represented by general formula VII: wherein, B represents a base moiety of nucleic acid wherein said base moiety may be optionally substituted with one or more substituents, R 3  and R 4  represents independently of each other a hydrogen atom or a C 1-6  alkyl group which may be optionally substituted with one or more substituents, each R 5  represents independently a hydrogen atom, or a C 1-6  alkyl group which may be optionally substituted with one or more substituents, each R 6  represents independently a hydrogen atom, or a C 1-6  alkyl group which may be optionally substituted with one or more substituents, R 7  represents a hydrogen atom or a protecting group for hydroxy group, R 8  represents a hydrogen atom, a phosphate group which may be optionally substituted with one or more substituents, or a thiophosphate group which may be optionally substituted with one or more substituents, and R 9 , R 10  and R 11  represent independently of each other a hydrogen atom, a C 1-6  alkyl group which may be optionally substituted with one or more substituents, or a protecting group for amino group, and m is an integer of 1 to 3, the method comprising the step according to  claim 23 .
