WebThe DMTr cation was then determined spectrophoto-metrically at 498 nm (ε 498 = 70 000 l mol –1 cm –1). The method was found to be useful for the determination of solid-supported amino groups and for monitoring the functionalisation of polymer supports used for the synthesis of peptides and oligonucleotides. WebVarious conditions for optimum detritylation (i.e., the removal of 5'-O-trityl protecting groups) during solid-phase synthesis of oligodeoxyribonucleotides were investigated. Di- and tri-chloroacetic acids of variable concentrations were used to study the removal of the 4,4'-dimethoxytrityl (DMTr) group. It was found that the DMTr group could ...

Dimethoxytrityl (DMTr) can be removed by a weak acid. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The hydrophilic PEG spacer increases solubility in aqueous media.
