PROCEDURE

实验过程

The 5′-O-DMT group is removed as per known literature procedures 4,4′-dimethoxytrityl ethers are commonly removed under acidic conditions (Oligonucleotides and analogues, A Practical Approach, Eckstein, F., ed, IRL Press, New York.) Generally, Compound 8 (1 eq.) is dissolved in 80% aqueous acetic acid. After several hours, the mixture is evaporated, dissolved in ethyl acetate and washed with a sodium bicarbonate solution. Purification by silica gel chromatography will give compound 9.
