or an enantiomer thereof, which is a monomer that can be used for the production of a single-stranded nucleic acid molecule capable of suppressing the expression of a target gene, can be obtained by: reacting a compound represented by formula (1):
or an enantiomer thereof with 6-hydroxyhexanoic acid in a solvent in the presence of an additive such as 1-hydroxybenzotriazole and a condensing agent, and then mixing the resultant reaction mixture, water, and a base such as alkali metal hydroxide to produce a compound represented by formula (2) :
or an enantiomer thereof; and reacting the compound represented by formula (2) or an enantiomer thereof with 2-cyanoethyl-N,N,N',N'-tetraisopropylphosphorodiamidite in a solvent in the presence of a coupling activator such as a diisopropylaminetetrazole salt.
摘要:
An amide compound represented by formula (I) has an excellent pest control effect. (In the formula, Y represents a 3-7 membered saturated heterocyclic ring which contains, as ring-forming component(s), one or more atoms or groups that are selected from the group consisting of an oxygen atom and -S(O) t -, the saturated heterocyclic ring may have one to three atoms or groups selected from group D and t represents 0 or the like; X represents a C 1 -C 8 chain hydrocarbon group having one group that is selected from group A; W represents -CR 8 - or the like; r represents 1 or the like; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 may be the same or different and each represents a hydrogen atom or the like; and n represents 1 or the like.)
