Connected nucleophilic substitution-Claisen rearrangement in flow – Analysis for kilo-lab process solutions with orthogonality

The two-step synthesis of phenol to 2-allylphenol in micro flow is investigated. This synthesis involves a nucleophilic substitution (SN2) reaction of phenol with allyl bromide towards allyl phenyl ether and the thermal Claisen rearrangement of allyl phenyl ether to 2-allylphenol. This carbon-carbon bond forming reaction route would provide a valuable path towards complex molecules. Flow cascades have turned into a powerful approach to provide chemical diversity (process-design intensification). This is enabled by chemical intensification of the Claisen rearrangement in micro flow, by reducing the reaction time to minutes without the need of a catalyst. While both individual reaction steps have been optimized separately in earlier research, an initial directly connected two-step synthesis gave low selectivity.Accordingly, the main topic investigated is how to achieve orthogonality in case of reagent mismatch between the two reactions. First, four flow process protocols using three different kinds of in-flow separation and one kinetic approach, are developed at laboratory scale. From there, process design sheets for kilolab processing set-ups of the suited approaches are developed which shed first light on their industrial practicality. In particular, it has been found that the main causes for the drop in selectivity are the presence of the base DBU and the reactant allyl bromide during the Claisen rearrangement. Three of the four investigated separation approaches demonstrated the ability to improve the overall yield – acid-base extraction, acid absorption by using ion exchange resin, using heterogeneous base, and dilution as kinetic approach. Finally, for every option, the proposed respective production set-up, anticipated advantages and drawbacks are given to facilitate a decision.

NMR reporter screening for the detection of high-affinity ligands

Binding is good, displacing is better. By adding a weakly binding reporter ligand to a mixture of protein and test compounds, NMR screening can identify strongly binding ligands by observing the displacement of the reporter ligand. For example, NMR screening identified, as a reporter ligand, a small fragment, 2-acetylbenzofuran (1, gray skeleton), which binds to the active site of 3alpha-HSD. A molecular model of the complex between 3alpha-HSD and 1 is shown.

Inhibition of the Cysteine Protease Human Cathepsin L by Triazine Nitriles: Amide???Heteroarene pi-Stacking Interactions and Chalcogen Bonding in the S3 Pocket

We report an extensive ?heteroarene scan? of triazine nitrile ligands of the cysteine protease human cathepsin L (hCatL) to investigate pi-stacking on the peptide amide bond Gly67?Gly68 at the entrance of the S3 pocket. This heteroarene???peptide bond stacking was supported by a co-crystal structure of an imidazopyridine ligand with hCatL. Inhibitory constants (Ki) are strongly influenced by the diverse nature of the heterocycles and specific interactions with the local environment of the S3 pocket. Binding affinities vary by three orders of magnitude. All heteroaromatic ligands feature enhanced binding by comparison with hydrocarbon analogues. Predicted energetic contributions from the orientation of the local dipole moments of heteroarene and peptide bond could not be confirmed. Binding of benzothienyl (Ki=4 nm) and benzothiazolyl (Ki=17 nm) ligands was enhanced by intermolecular C?S???O=C interactions (chalcogen bonding) with the backbone C=O of Asn66 in the S3 pocket. The ligands were also tested for the related enzyme rhodesain.
