The 5'-DMT prevents polymerization of the nucleoside during functionalization of the solid support resin.

WebThe dimethoxytrityl (DMT) protecting group is widely used for protection of 5'-hydroxy group in nucleosides, particularly in oligonucleotide synthesis, such as in the phosphite triester method of solid phase DNA synthesis shown above. WebAbstract. The kinetics and mechanism of the deprotection (detritylation) of 5′- O - (4,4′-dimethoxytrityl)-2′-deoxythymidine nucleoside catalysed by dichloroacetic acid to give a …
WebDMT is a blocking group that protects the 5′ hydroxyl, preventing off-target reactions. DMT attaches the incoming base to the solid silica support, immobilizing the base. DMT activates the base at the 5′ position, promoting a reaction with the 3′ end of an incoming base. WebJan 30, 2024 · Finally, removal of tert-butyldimethylsilyl and dimethoxytrityl groups by treatment with triethylamine trihydrofluoride, followed by RP-HPLC purification, gave the desired products 1a and 2a. The two diastereomers of the phosphorothioate product 2a were separable by RP-HPLC and were assigned absolute configurations based on their …
