4-Cyano-2-butenyl (CB) is a new type of protectinggroup 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.
