4-Cyano-2-butenyl (CB) is a new type of protecting group for the internucleotidic bonds in the synthesis of oligodeoxyribonucleotides by the phosphoramidite approach. This group is stable to acidic conditions and can be removed under mild conditions by a δ-elimination pathway using aqueous ammonium hydroxide.
4-氰基-2-丁烯基(CB)是通过亚磷酰胺方法合成寡脱氧核糖核苷酸中核苷酸间键的新型保护基。该基团对酸性条件稳定,在温和条件下可通过使用氢氧化铵水溶液的δ消除途径除去。
