Phenanthrene, a Polycyclic Aromatic Hydrocarbon, remains adsorbed to sedimentary particles in aquatic environments. It affects mainly benthic organisms, and is considered potentially genotoxic. In ecotoxicology, species of Chironomus Meigen, 1803 are

Two bis-trifluoromethyl pepstatin A analogues, carboxylic acid 1 and its methyl ester 2, have been synthesised in order to probe the properties and size of the trifluoromethyl (Tfm) group and compare it to the "bigger" isobutyl that is present in pep

A novel synthesis of enantiopure hydroxyethylamine isosteres 1 has been developed. Reaction of lithiated β-sulfinylethylamines 3 with N-Cbz-imines generated in situ from α-amino-sulfones 4 afforded in good to excellent yields and moderate stereocon

This article describes a new, useful synthetic tool, the “Non-Oxidative” Chloro-Pummerer Reaction (NOCPR), which allows for the use of enantiomerically pure α-Li alkylsulfoxides as chiral α-chloroalkyl carbanions with N-protected imines. In thi

This paper reviews the solution-phase synthesis of trifluoromethyl (Tfm)-analogues of bioactive peptides, such as RGD-peptides and the aspartyl protease inhibitor pepstatin, and the solution/solid-phase synthesis of Tfm-substituted retro- and retro-i

Enantiomerically pure α-Li alkyl-sulfoxides can be used as chiral α-chloroalkyl carbanions with N -protected imines by means of the ‘non-oxidative’ chloro-Pummerer reaction (NOCPR). This novel methodology allows for a one-pot displacement of a

Two efficient approaches to both enantiomers of syn-γ-trifluoromethyl γ-amino β-hydroxy butyric acid (γ-Tfm-GABOB) (10), a new hydroxymethylene (statine) dipeptide isostere, are described. One exploits the recently disclosed `non-oxidative' Pumme
