, p. 921 - 927 (2018/09/22)
1,3-Oxazolidin-5-ones derived from both enantiomers of proline and trichloroacetaldehyde were prepared and applied as an amine component in the synthesis of chiral predictive triazine-based coupling reagents. The reagents were found to be useful in condensations yielding enantiomerically enriched products from racemic substrates.

The rational design and implementation of enantiodivergent enamine catalysis is reported. A simple secondary amine catalyst, 2-methyl-l-proline, and its tetrabutylammonium salt function as an enantiodivergent catalyst pair delivering the enantiomers of α-functionalized aldehyde products in excellent enantioselectivities. This novel concept of designed enantiodivergence is applied to the enantioselective α-amination, aldol, and α-aminoxylation/α-hydroxyamination reactions of aldehydes.

A radical based synthesis of a broad variety of protected enantiopure α-amino acids, including fluorinated derivatives, is described. The radical addition furnishes naturally latent mercapto-α-amino acids ideally equipped for native chemical ligation.
STRUCTURAL MIMETICS OF PROLINE-RICH PEPTIDES AND USE THEREOF
-
Paragraph 0110-0117, (2015/02/18)
The invention relates to compounds that can be used, in particular, as structural mimetics of proline-rich peptides and are correspondingly able to bond with proline-rich-motif binding domains (PRM domains) of proteins. The invention further relates to the use of these compounds as pharmaceutically active agents, as well as the use of the pharmaceutically active agents for the treatment of bacterial, neurodegenerative and tumor diseases.

With the aim of developing polyproline type II helix (PPII) secondary-structure mimetics for the modulation of prolin-rich-mediated protein-protein interactions, the novel diproline mimetic ProM-2 was designed by bridging the two pyrrolidine rings of a diproline (Pro-Pro) unit through a Z-vinylidene moiety. This scaffold, which closely resembles a section of a PPII helix, was then stereoselectively synthesized by exploiting a ruthenium-catalyzed ring-closing metathesis (RCM) as a late key step. The required vinylproline building blocks, that is, (R)-N-Boc-2-vinylproline (Boc=tert-butyloxycarbonyl) and (S,S)-5-vinylproline-tert-butyl ester, were prepared on a gram scale as pure stereoisomers. The difficult peptide coupling of the sterically demanding building blocks was achieved in good yield and without epimerization by using 2-(1H-7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU)/N,N-diisopropylethylamine (DIPEA). The RCM proceeded smoothly in the presence of the Grubbs II catalyst. Stereostructural assignments for several intermediates were secured by X-ray crystallography. As a proof of concept, it was shown that certain peptides containing ProM-2 exhibited improved (canonical) binding towards the Ena/VASP homology 1 (EVH1) domain as a relevant protein interaction target.
