5'-O-Dimethoxytrityl-(N-acyl)-2'-deoxyribonucleosides afford 3'-O-formyl-(N-acyl)-2'-deoxyribonucleosides Ia-Id by the action of formic acetic anhydride followed by the action of 80percent aqueous acetic acid.The formyl group is removed from Ia-Id by treatment with 1 mol l-1 triethylamine. 3'-O-Formyl-2'-deoxythymidine (Ia) gives 3'-O-dimethoxytrityl-2'-deoxythymidine (V) by subsequent treatment with acetic anhydride, triethylamine, dimethoxytrityl chloride and methanolic ammonia.The use of compounds I for the synthesis of d-GGAGG (XIX) and d-T16 (XXXII) is described.Systems for thin-layer chromatography of 5'-O-dimethyltrityl-oligodeoxyribonucleotides on silica gel are described.
