Fmoc-Amox, A Novel Reagent for Fmoc-Protection
The most common reagent for the Fmoc-protection of amino acids is currently Fmoc-OSu, followed by Fmoc-Cl. However, the use of these reagents is usually accompanied by several side reactions, such as the formation of beta-alanine and dipeptides.

Lysine Dendrons
We now offer a series of Lysine dendrons for chemoselective functionalization of molecules containing carbonyl groups. These multivalent molecules carry diverse types of moieties, such as amine- or hydroxyl-groups, DOTA chelators or triphenylphosphonium (TPP) cations.
