Fmoc-Lys(ivDde)-OH – Acid/Base Stable Protection for Special Use

The side chain protecting group ivDde on Lysine is stable to piperidine/DMF and TFA but would be easily removed by hydrazine/DMF solution, which enables the side-chain protecting groups of other amino acid residues keep untouched when deprotecting this group. This strategy would be very useful for synthesis of cyclic and branched peptides with site-specific modifications.
