Authors: Tressler CM, Zondlo NJ

Abstract
(2S,4R)- and (2S,4S)-perfluoro-tert-butyl 4-hydroxyproline were synthesized (as Fmoc-, Boc-, and free amino acids) in 2-5 steps. The key step of each synthesis was a Mitsunobu reaction with perfluoro-tert-butanol, which incorporated a perfluoro-tert-butyl group, with nine chemically equivalent fluorines. Both amino acids were incorporated in model ?-helical and polyproline helix peptides. Each amino acid exhibited distinct conformational preferences, with (2S,4R)-perfluoro-tert-butyl 4-hydroxyproline promoting polyproline helix. Peptides containing these amino acids were sensitively detected by (19)F NMR, suggesting their use in probes and medicinal chemistry.

Related Articles Fluorinated Aromatic Amino Acids are Sensitive 19F NMR Probes for Bromodomain-Ligand Interactions. ACS Chem Biol. 2014 Oct 7; Authors: Mishra NK, Urick AK, Ember S, Schonbrunn E, Pomerantz WC Abstract We describe a 19F NMR method for detecting bromodomain-ligand interactions using fluorine-labeled aromatic amino acids due to the conservation of aromatic residues in the bromodomain binding site. We test the...

[Question from NMRWiki Q&A forum] 13C quaternary centers in amino acids
13C quaternary centers in amino acids I've got a sample of about 5mg of an amino acid that is the final product of a a synthesis. Due to the long relaxation time that the carboxylic and the alpha C we only got a 200 varian Mercury instrument and we're unable to obtain those signals. I was wondering if an APT is better than DEPT, because we're only interested in this signals and i've heard the overall pulse sequence is shorter than the DEPT, increasing the number of scans in the same period of time. Check if somebody has answered this question on NMRWiki QA forum

[KPWU blog] Names of Atoms of Amino acids
Names of Atoms of Amino acids I really hate the inconsistent nomenclature of atoms of amino acids between different programs/database. I finished all NOESY assignment on Sparky using PDB nomenclature and the Sparky XPLOR constraint plugin (shortcut xf) doesn’t take care of the differences between XPLOR and PDB. Thus I have to find a table showing me the differences of names http://stats.wordpress.com/b.gif?host=kpwu.wordpress.com&blog=76132&post=262&subd=kpwu&ref=&feed=1 Go to KPWU blog to read complete post.
