Modulation of Ferrocene–Ferrocene Interactions by Varying Their Reciprocal Positions in L-Dap/Aib Helical Peptides

open access: yesInorganics, 2023
In this work, we developed two new polyfunctional hybrid systems in which the presence of Fc redox “antennas” on peptide scaffolds allows for a modulation of their electronic properties.

Rapid and efficient synthesis of peptide fragments containing α- aminoisobutyric acid using Fmoc-amino acid chlorides/potassium salt of 1- hydroxybenzotriazole [PDF]

open access: yes, 1998
The synthesis of peptides containing multiple Aib residues was accomplished using Fmoc-Aib-Cl in presence of KOBt. As no additional base was added, the duration of coupling reactions could be extended. Thus, the synthesis of the alamethicin 1-4 fragment,
