Org Biomol Chem. 2017 Oct 25;15(41):8788-8801. doi: 10.1039/c7ob02259j.

A strategy for the synthesis of biologically relevant 5-hydroxy-imidazolidine-2-thione derivatives is presented. A novel class of α-sulfonylamines have been suitably prepared (46-81% yield) as precursors of formal benzylidenethiourea acceptors; these are generated in situ and intercepted by N-heterocyclic carbene...

Nucleophilic and electrophilic double aroylation of chalcones with benzils promoted by the dimsyl anion as a route to all carbon tetrasubstituted olefins.

J Org Chem. 2015 Feb 06;80(3):1937-45. doi: 10.1021/jo502582e. Epub 2015 Jan 09.

Dimsyl anion promoted the polarity reversal of benzils in a Stetter-like reaction with chalcones to give 2-benzoyl-1,4-diones (double aroylation products), which, in turn, were converted into the corresponding tetrasubstituted olefins via aerobic oxidative dehydrogenation catalyzed by Cu(OAc)2.

Oxygenation by ruthenium monosubstituted polyoxotungstates in aqueous solution: experimental and computational dissection of a Ru(III)-Ru(V) catalytic cycle.

Molecular polyoxometalates with one embedded ruthenium center, with general formula [Ru(II/III)(DMSO)XW11O39](n-) (X = P, Si; n = 4-6), are readily synthesized in gram scale under microwave irradiation by a flash hydrothermal protocol. These nanodimensional and polyanionic complexes enable aerobic...

The influence of the localised charge of C- and N-termini on peptide self-assembly.

Soft matter

Bortolini C, Jones NC, Hoffmann SV, Besenbacher F, Dong M.
PMID: 26472087
Soft Matter. 2016 Jan 14;12(2):373-7. doi: 10.1039/c5sm01669j.

The charge of a peptide influences final assembled structures. It is important to consider not only global charge, but also local, such as that found on the terminal residues. This work investigates the change of peptide self-assembly through the...

Photoexcited structural dynamics in azo-compounds may differ fundamentally whether the push-pull photochromic azo-compound is isolated or forms a heterogeneous charge transfer complex, due to a sudden oxidation of the chromophore. Herein, we use a quantum-classical self-consistent approach that incorporates...
