- Chemical labeling strategy with (R)- and (S)-trifluoromethylalanine for solid state 19F NMR analysis of peptaibols in membranes
-
(Figure Presented) Substitution of a single Aib-residue in a peptaibol with (R)- and (S)-trifluoromethylalanine yields two local orientational constraints θ by solid state 19F NMR. The structure of the membrane-perturbing antibiotic alamethicin

- Fluorine-containing α-alkynyl amino esters and access to a new family of 3,4-dehydroproline analogues
-
New α-alkynyl, α-CF3 amino esters have been prepared from electrophilic imines and used to produce 3-alkenyl-3,4-dehydroproline derivatives, via enyne metathesis with the precatalyst [Ru=C=C=CPh2(Cl)(PCy3)(arene)]O3/

-
New synthetic pathways to 3,3,3-trifluoroalanine, 2-deutero-3,3,3-trifluoroalanine, their esters, amides, and thioamides are described, starting from hexafluoroacetone, and trifluoropyruvates, respectively.
