General description

A highly efficient coupling reagent for solid and solution phase peptide synthesis. In comparative studies HATU has been found to give better coupling yields with less enantiomerization that HBTU, TBTU or PyBOP®[1,2,3]. It is particularly effective at coupling to N-alkyl amines where other coupling reagents give poor yields and is the preferred reagent for loading resins bearing secondary amino groups.
