Compounds of the following general formula (1) and salts thereof:
where A represents an alkylene group having 1 to 2 carbon atoms, etc.; B represents an aromatic heterocyclic group which may have a substituent, etc.; R
1
and R
2
each represent a hydrogen atom, a protective group for a hydroxyl group for synthesis of nucleic acid, a phosphate group, or —P(R
4
)R
5
[where R
4
and R
5
are the same or different, and each represent a hydroxyl group, a hydroxyl group protected with a protective group for synthesis of nucleic acid, a mercapto group, a mercapto group protected with a protective group for synthesis of nucleic acid, etc.]; and R
3
represents a hydrogen atom, a halogen atom, a hydroxyl group, a hydroxyl group protected with a protective group for synthesis of nucleic acid, etc.
These compounds are useful for producing oligonucleotide analogues useful for the antisense method, antigene method, etc., and for producing their intermediates.
