Statins are essential naturally occurring β-hydroxy-γ-amino acids and (3S,4S)-Statine, derived from L-Leucine, is found in important aspartic proteases inhibitors like Pepstatin A. We developed a new synthesis of (3S,4S)-Statine based on the highly

Enantiopure α-Tfm-proline and α-Tfm-pipecolic acid were synthesized starting from commercially available diesters and ethyl trifluoroacetate. A Strecker type reaction on intermediate chiral Tfm-oxazolo-pyrrolidine and -piperidine provided the corre

The straightforward synthesis of enantiopure 5-(R)-and 5-(S)-trifluoromethylproline is reported. The key steps are a Ruppert-Prakash reagent addition on l-pyroglutamic esters followed by an elimination reaction and a selective reduction. The solution

Fluorinated non-natural amino acids are useful tools for improving the bioavailability of peptides but can also serve as fluorinated probes in 19 F NMR-based enzymatic assays. We report herein that the use of the non-natural α-quaternarized (R)-α-t

A straightforward synthesis of enantiopure α-trifluoromethyl aziridine-2-carboxylic acid (α-TfmAzy) is reported from a trifluoropyruvate derived enantiopure oxazolidine. A key Strecker-type synthetic step and a late cyanide basic hydrolysis gave th

In order to achieve accurate determination of the local hydrophobicity increases in peptide sequences produced by incorporation of trifluoromethylated amino acids (TfmAAs), the chromatographic hydrophobicity indexes (ϕ0 ) of three series of tripepti

Among the fluorinated noncanonical amino acids, l-trifluoromethionine (TFM) and l-S-(trifluoromethyl)cysteine (TfmCys), fluorinated analogues of methionine and cysteine, are of particular interest because of their ability to locally increase the hydr

Considering the increasing importance of fluorinated peptides, the development of efficient and reliable synthetic methods for the incorporation of unnatural fluorinated amino acids into peptides is a current matter of interest. In this study, we rep
