Applications
TBDC (3-(((tert-butylimino)methylene)amino)-N,N-dimethylpropan-1-amine) salts represent a new generation of water- and organic-solvent-compatible coupling agents for peptide bond formation. These next-generation CDIs overcome key limitations of traditional reagents like EDC·HCl and DIC, offering:
- Minimal protection synthesis compatible. No need for protecting groups on His, Trp, Ser, Tyr, Thr
- High conversion (>95%) and low racemization (L:D > 95:5)
- Compatible with green solvents: EtOAc, 2-MeTHF, GVL, DMC
- Suitable for both manual and automated synthesis
- Forms open-chain stable intermediates unlike EDC
TBDC salts enable highly efficient amide bond formation in solution-phase, solid-phase, TAG – assisted LPPS ( TAPS) and green chemistry processes, eliminating the need for histidine and tryptophan side-chain protection in many cases.
