Chemical Properties
white to light yellow powder
Uses
HBTU is a coupling reagent used in peptide synthesis. HBTU has been shown to effectively suppress racemization.
reaction suitability
reaction type: Coupling Reactions
Biological Activity
hbtu (2-(1h-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexauorophosphate), a coupling reagent commonly used in solid phase peptide synthesis. after being introduced in 1978, this agent shows popularity in chemistry and industry use due to its mild activating properties. moreover, it also shows resistance against racemization. low tendency for racemization is a key requirement for peptide synthesis. especially for solid phase peptide synthesis, quantitative yields with short reaction times are crucial in order to make the synthesis of large peptides feasible. [1]
Synthesis
HBTU is synthesized by reaction of HOBt with TCFH under basic conditions.
in vitro
peptide synthesis relied mostly on efficient and safe coupling reagents. hbtu was proved to transform carboxylic acids into azides efficiently and practically. the process might be applied to a wide range of carboxylic acids including n-protected amino acids. in addition, hbtu was of great value in one-pot synthesis of dipeptidyl urea esters, ureas, and carbamates from acids. the advantages of hbtu included the following points: 1) non-explosive and therefore more suitable for solution/solid phase peptide synthesis. 2) high solubility and stability in classical solvents. 3) feasible for colorimetric reaction monitoring. [2]
Purification Methods
Wash the salt with H2O (3x), CH2Cl2 (3x), dry and recrystallise it from MeCN. Dry it in a vacuum and store it cold in the dark [Dourtoglou et al. Tetrahedron Lett 1269 1978, NMR: Dourtoglou and Gross Synthesis 572 1984]. Benzoxazolinone (2 -hydroxybenzoxazole) [59 -49 -4] M 135.1, m 137 -139o, 142 -143o(corrected), b 121-213o/17mm, 335-337o/760mm. Benzoxazolinone is purified by recrystallisation from aqueous Me2CO followed by distillation at atmospheric pressure, then in a vacuum. The methyl mercury salt recrystallises from aqueous EtOH and has m 156-158o. [Bywater et al. J Am Chem Soc 67 905 1945, Beilstein 27 III/IV 2677.]
