O-(Benzotriazol-1-yl)-N,N,N',N'-Tetramethyluronium Tetrafluoroborate (TBTU) (CAS: 125700-67-6) is used as coupling reagent for solid phase peptide synthesis.
An ideal solid-phase peptide synthesis coupling reagent; The crystal and Solution structure of the coupling reagent is guanidine Salt N-oxide, and not an uronium compound.
TBTU has been used to study ten different phosphonium and uronium salt-based coupling reagents, which are used to synthesize four peptides. TBTU has been documented as a coupling reagent to synthesize a tetrahydrocarbazole substituted dipeptide in a multi-gram solid-phase synthesis. The compound has also been incorporated with HOBt (hydroxybenzotriazole dihydrate) as a carboxyl activator before the coupling of a C-terminal amino acid with a success rate of 100% coupling.
TBTU is one of the most popular in situ activation reagents in solid and solution phase peptide synthesis. In addition to having high reactivity, TBTU have also been shown to limit enantiomerization during fragment condensation.
