Applications
- Recent studies show that crystal as well as solution structure of this coupling agent is a guanidinium N-oxide and not an uronium compound.
- HBTU is attributed to various advantages, such as -very low racemization, simple reaction conditions, very short reaction time, and high yields.
Studies
- HBTU mediated 1-hydroxybenzotriazole (HOBt) conjugate addition: synthesis and stereochemical analysis of β-benzotraizoleN-oxide substituted γ-amino acids and hybrid peptides
