Published: September 2010

A click end-capping reaction exploiting nitrile N-oxide to rotaxane was described with emphasis of productivity of the protocol via stable C-C bond formation. Establishment of a pH-driven molecular shuttling system was also demonstrated by practical neutralization of the sec-ammonium group of the rotaxane axle with potassium hydroxide.

This study tackles the challenge of enantiodifferentiation of nitrile compounds, which is typically difficult to resolve using nuclear magnetic resonance (NMR) due to the significant distance between the chiral center and the nitrogen atom involved in molecular interactions. We have developed novel chiral F-labeled probes, each featuring two chiral centers, to exploit the "match-mismatch" effect, thereby enhancing enantiodiscrimination. This strategy effectively differentiates chiral analytes with quaternary chiral carbon centers as well as those with similar substituents at the chiral center.

Accumulation of misfolded proteins challenges cellular proteostasis and is implicated in aging and chronic disorders. Cancer cells, moreover, face an elevated level of basal proteotoxic stress; hence, exacerbating endoplasmic reticulum (ER) stress has been shown to induce programmed cell death while enhancing anticancer immunogenicity. We hypothesize that hydrophobic abiotic macromolecules can trigger a similar stress response.

Continuous flow technology was exploited for the effective generation of nitrile imines via photolysis of substituted aryl tetrazoles. The resulting photo-click process rapidly affords advanced nitrogen-rich scaffolds upon the subsequent trapping of the reactive dipole with alkenes, alkynes, and benzylic amines. Crucially, this approach uncovers the differential reactivity for ether vs amine tethers, thus providing facile and scalable access to underexplored medicinally relevant heterocyclic entities.

Organolithium reagents, known for their low cost, ready availability, and high reactivity, allow fast cross-coupling under ambient conditions. However, their direct cross-coupling with fluoroalkyl electrophiles remains a formidable challenge due to the easy formation of thermo-unstable fluoroalkyl lithium species during the reaction, which are prone to decomposition via rapid α/β-fluoride elimination. Here, we exploit heteroatom-stabilized allylic anions to harness the exceptional reactivity of organolithium reagents, enabling the compatibility of difluoroalkyl halides and facilitating versatile and precise fluorine functionality introduction under mild conditions.

A profound understanding of protein structure and mechanism requires dedicated experimental and theoretical tools to elucidate electrostatic and hydrogen bonding interactions in proteins. In this work, we employed an approach to disentangle noncovalent and hydrogen-bonding electric field changes during the reaction cascade of a multidomain protein, i.e.
