ChemPlusChem 1/2014: New Features to Delight our Readers
In this issue, Petr Cigler, T. Govindaraju, and Radim Beranek are the first authors to feature as part of the new Early Career Series. Also, Petr Cigler was selected to give the inaugural interview, in which he discusses his career and research achievements. Of course the popular Cover Profiles continue, and an article on efficient DNA triplex–forming oligonucleotides by Vyacheslav Filichev and Carlos González is highlighted this month.

- Chemical Synthesis of Asparagine-Linked Archaeal N-Glycan from Methanothermus fervidus
Someswara Rao Sanapala and Prof. Dr. Suvarn S. Kulkarni
Article first published online: 11 MAR 2014 | DOI: 10.1002/chem.201304950
Sweetening up: Herein the first total synthesis of archaeal L-asparagine linked hexasaccharide from Methanothermus fervidus using a highly convergent [3+3] glycosylation approach in high overall yields is reported (see scheme). The synthesis relies on efficient preparation of regioselectively protected thioglycoside building blocks for orthogonal glycosylations and late-stage N-aspartylation.
- Palladium-Catalyzed Alkoxycarbonylation of Terminal Alkenes to Produce α,β-Unsaturated Esters: The Key Role of Acetonitrile as a Ligand
Prof. Dr. Andrei V. Malkov, Nolwenn Derrien, Dr. Maciej Barłóg and Prof. Dr. Pavel Kočovský
Article first published online: 11 MAR 2014 | DOI: 10.1002/chem.201304798
Acetonitrile is the key! A mild protocol has been developed for the PdII-catalyzed alkoxycarbonylation of terminal olefins to produce α,β-unsaturated esters with a wide range of substrates (see scheme). Key features are the use of MeCN as a solvent (and/or ligand) to control the reactivity of the intermediate Pd complexes and the combination of CO with O2, which facilitates the CuII-mediated reoxidation of Pd0 to PdII and prevents double carbonylation.
- Trapping of Organophosphorus Chemical Nerve Agents in Water with Amino Acid Functionalized Baskets
Yian Ruan, Erdin Dalkiliç, Paul W. Peterson, Aroh Pandit, Prof. Arif Dastan, Jason D. Brown, Shane M. Polen, Prof. Christopher M. Hadad and Prof. Jovica D. Badjić
Article first published online: 11 MAR 2014 | DOI: 10.1002/chem.201304779
Nervous trapping: The binding affinity (Ka) of amino acid functionalized baskets toward dimethyl methylphosphonate (DMMP) guest, akin in size to the chemical nerve-agent sarin, is a function of the size of substituents R groups at the basket′s rim. In particular, the greater degree of branching at the first carbon atom of each substituent lowers the host affinity toward DMMP (see figure).
- Exploring the Synthesis of a New Group of Chiral Ammonium Salts with Specific Configurations at the Stereogenic Nitrogen Centers
Dr. Prisca K. Eckert, Christopher Golz, Dr. Patrick Degen, Cornelia Werner, Prof. Dr. Heinz Rehage and Prof. Dr. Carsten Strohmann
Article first published online: 11 MAR 2014 | DOI: 10.1002/chem.201304433
A group of new chiral dications with a fixed, specific configuration at the stereogenic nitrogen center was created (see scheme). Stereoselective synthesis and recrystallization give the diastereomerically and enantiomerically pure dications, including a chiral amphiphile with surface-active properties.
- Ruthenium/Imidazolylphosphine Catalysis: Hydrogenation of Aliphatic and Aromatic Nitriles to Form Amines
Svenja Werkmeister, Dr. Kathrin Junge, Bianca Wendt, Dr. Anke Spannenberg, Dr. Haijun Jiao, Christoph Bornschein and Prof. Dr. Matthias Beller
Article first published online: 11 MAR 2014 | DOI: 10.1002/chem.201303989
It’s not complicated: A general and easy homogeneous catalyst system based on [Ru(cod)(methylallyl)2] and a cyclohexyl-substituted imidazolylphosphine ligand for selective hydrogenation of aliphatic nitriles is presented. In addition, by using an isopropyl-substituted imidazolylphosphine ligand, selected aromatic nitriles were reduced with excellent yields towards the primary amine. Furthermore, two new crystal structures give an insight of possible pre-catalysts.
