Cluster Preface: Non-Covalent Interactions in Asymmetric Catalysis [PDF]
, 2016 The successful harnessing of non-covalent interactions to activate functional groups and control selectivity in chemical reactions is a relatively recent phenomenon in synthetic chemistry, but one that has delivered ground-breaking results, particularly ...

Amyloid peptide mixtures: self-assembly, hydrogelation, nematic ordering and catalysts in aldol reactions [PDF]
, 2020 Morphological, spectroscopic and scattering studies of the self-assembly and aggregation process of mixtures of [RF]4 and P[RF]4 peptides (where: R = arginine; F = phenylalanine; P = proline), in solution and as hydrogels, were performed to obtain ...

Advanced Science, EarlyView.Rapid detection of explosives is essential for public safety and national security. Here, conjugated polymers (SPs), incorporating pentiptycene with organosulfur side chains, have been reported using sulfur(VI)‐fluoride exchange (SuFEx). The SP‐7 polymer exhibited exceptional fluorescence quenching (>99% in 60 s) for detecting nitroaromatic explosives.

Thiosemicarbazone organocatalysis:Tetrahydropyranylation and 2-deoxygalactosylation reactions and kinetics-based mechanistic investigation [PDF]
, 2017 Thiosemicarbazones are introduced as a new class of highly tunable and efficient organocatalysts. We showcase this by studies of the tetrahydropyranylation reaction, where insights to the mechanism was achieved by a double Hammett analysis of both the ...

Mechanochemical Organocatalysis: Do High Enantioselectivities Contradict What We Might Expect?
ChemSusChem, 2021 Ball mills input energy to samples by pulverising the contents of the jar. Each impact on the sample or wall of the jar results in an instantaneous transmission of energy in the form of a temperature and pressure increase (volume reduction).

Synthesis of Crosslinked Biopolyesters Catalyzed by Natural Amino Acids
Asian Journal of Organic Chemistry, EarlyView.Highly crosslinked bio‐polyesters were synthesized via the ROCOP reaction between epoxidized sunflower oil and biobased cyclic anhydrides. The resulting materials were comprehensively characterized by FT‐IR, TGA, and DSC. A cross‐linked network in the bio‐based polymers has been confirmed by dynamic mechanical analysis.
