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.; R1 and R2 each represent a hydrogen atom, a protective group for a hydroxyl group for synthesis of nucleic acid, a phosphate group, or -P(R4)R5 [where R4 and R5 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 R3 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.
以下通用式(1)及其盐的化合物:其中A代表具有1至2个碳原子的烷基基团等;B代表可能具有取代基的芳香杂环基团等;R1和R2分别代表氢原子,用于核酸合成的羟基保护基,磷酸基,或-P(R4)R5 [其中R4和R5相同或不同,每个代表羟基,用于核酸合成的羟基保护基,巯基,用于核酸合成的巯基保护基等];R3代表氢原子,卤素原子,羟基,用于核酸合成的羟基保护基等。这些化合物可用于生产用于反义方法、抗基因方法等的寡核苷酸类似物,以及生产它们的中间体。
