Celebrating Young Chemists

Cover image for Vol. 20 Issue 34 Check out the special issue dedicated to young European chemists. This issue has been together to celebrate the past participants of the European Young Chemist Award (EYCA), presented at the first four EuCheMS Congresses, and to highlight the great diversity of research currently being conducted by young chemists from all over the world.

  1. Synthesis and Analysis of the Conformational Preferences of 5-Aminomethyloxazolidine-2,4-dione Scaffolds: First Examples of β2- and β2, 2-Homo-Freidinger Lactam Analogues

    Arianna Greco, Sara Tani, Rossella De Marco and Luca Gentilucci

    Article first published online: 2 SEP 2014 | DOI: 10.1002/chem.201402519

    Peptides with a twist: The expedient ring closure of an isoSer residue within a peptide sequence allows the preparation of peptidomimetics containing constrained aminomethyloxazolidine-2,4-dione scaffolds, novel mixed β/α-dipeptides, and β2-homo variants of Freidinger lactams, which can be equipped with a proteinogenic side chain at all residues (see scheme).

  2. From Eight-Membered 10π Electron Sulfur–Nitrogen Cycles to Bicycles and Cages: A Theoretical Approach

    Prof.Dr. Rolf Gleiter, Prof.Dr. Gebhard Haberhauer and Sascha Woitschetzki

    Article first published online: 2 SEP 2014 | DOI: 10.1002/chem.201402481

    Simple rules for complex S–N compounds: A simple way of rationalizing the structures of cyclic, bicyclic, and tricyclic sulfur–nitrogen species and their congeners is presented. This procedure is summarized in two rules, which allow the reader to perceive, for example, why S4N4 (black) and the anion S4N5 (blue) prefer tricyclic cages whereas the cation S4N5+ (red) exists in bicyclic form (see graphic).

  3. Germylene Cyanide Complex: A Reagent for the Activation of Aldehydes with Catalytic Significance

    Rahul Kumar Siwatch and Dr. Selvarajan Nagendran

    Article first published online: 2 SEP 2014 | DOI: 10.1002/chem.201404204

    Reaction of a digermylene oxide complex [(L)GeOGe(L)] (1) with trimethylsilylcyanide (TMSCN) gave the first germylene monocyanide [GeCN(L)] (2) (L=aminotroponiminate). Compound 2 catalyzes the cyanosilylation of aldehydes by using TMSCN and has become the first isolable and structurally characterized germylene to act as a catalyst (see scheme).

  4. Super Sensitization: Grand Charge (Hole/Electron) Separation in ATC Dye Sensitized CdSe, CdSe/ZnS Type-I, and CdSe/CdTe Type-II Core–Shell Quantum Dots

    Tushar Debnath, Partha Maity and Dr. Hirendra N. Ghosh

    Article first published online: 1 SEP 2014 | DOI: 10.1002/chem.201403267

    Steady state and time-resolved luminescence studies as well as femtosecond time-resolved absorption measurements have shown that grand charge separation occurs in CdSe/ATC composite systems. The hole-transfer process has been found to be most efficient in CdSe QD. On the other hand, it has been found to be facilitated in CdSe/CdTe type-II and retarded in CdSe/ZnS type-I core–shell materials (see figure).

  5. Natural Compounds against Neurodegenerative Diseases: Molecular Characterization of the Interaction of Catechins from Green Tea with Aβ1–42, PrP106–126, and Ataxin-3 Oligomers

    Dr. Erika Sironi, Dr. Laura Colombo, Angela Lompo, Dr. Massimo Messa, Dr. Marcella Bonanomi, Dr. Maria Elena Regonesi, Dr. Mario Salmona and Dr. Cristina Airoldi

    Article first published online: 1 SEP 2014 | DOI: 10.1002/chem.201403188

    Green tea for memory: By combining NMR spectroscopy, transmission electron microscopy, and circular dichroism, the structural determinants involved in the interaction of green tea catechins with Aβ1–42, PrP106–126, and ataxin-3 oligomers have been identified. This data allow the elucidation of their mechanism of action, showing that the flavan-3-ol unit (see figure) of catechins is essential for their interaction.
