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. Translation of Dicarboxylate Structural Information to Fluorometric Optical Signals through Self-Assembly of Guanidinium-Tethered Oligophenylenevinylene

    Dr. Takao Noguchi, Dr. Bappaditya Roy, Dr. Daisuke Yoshihara, Dr. Youichi Tsuchiya, Dr. Tatsuhiro Yamamoto and Prof. Seiji Shinkai

    Article first published online: 18 SEP 2014 | DOI: 10.1002/chem.201404028

    Self-assembly married to molecular recognition: A novel assembly-based fluorescence (FL) sensory system exhibits characteristic FL responses toward L- and meso-tartarate, wherein different self-assembly processes are directed according to the molecular structural information (see figure). This utilization of self-assembly substantiates its potential ability to translate molecular information and thus opens up a new avenue of molecular recognition.

  2. Synthesis of Highly Substituted N-(Furan-3-ylmethylene)benzenesulfonamides by a Gold(I)-Catalyzed Oxidation/1,2-Alkynyl Migration/Cyclization Cascade

    M. Sc. Tao Wang, M. Sc. Long Huang, M. Sc. Shuai Shi, Dr. Matthias Rudolph and Prof. Dr. A. Stephen K. Hashmi

    Article first published online: 18 SEP 2014 | DOI: 10.1002/chem.201404229

    A rarely observed 1,2-alkynyl migration onto a gold carbenoid is a key step in the reaction pathway in the synthesis of a variety of N-(furan-3-ylmethylene)benzenesulfonamides by a gold(I)-catalyzed cascade reaction from easily accessible starting materials.

  3. Probing the Role of π Interactions in the Reactivity of Oxygen Species: A Case of Ethylzinc Aryloxides with Different Dispositions of Aromatic Rings toward the Metal Center

    Łukasz Mąkolski, Dr. Karolina Zelga, Dr. Rafał Petrus, Dominik Kubicki, Prof. Piotr Zarzycki, Prof. Piotr Sobota and Prof. Janusz Lewiński

    Article first published online: 18 SEP 2014 | DOI: 10.1002/chem.201403851

    Unprecedented events in the rich history of the oxygenation chemistry of alkylzinc compounds have been provided by employing well-defined ethylzinc aryloxides that purposefully bear a single phenyl substituent in the ortho position. These compounds were examined as a model system for dioxygen activation by using complexes with a nonredox active metal center (see figure).

  4. BrettPhos Ligand Supported Palladium-Catalyzed C[BOND]O Bond Formation through an Electronic Pathway of Reductive Elimination: Fluoroalkoxylation of Activated Aryl Halides

    T. M. Rangarajan, Dr. Rajendra Singh, Dr. Raju Brahma, Kavita Devi, Dr. Rishi Pal Singh, Dr. R. P. Singh and Prof. Dr. Ashok K. Prasad

    Article first published online: 18 SEP 2014 | DOI: 10.1002/chem.201404121

    C[BOND]O coupling: A BrettPhos ligand supported Pd-catalyzed C[BOND]O bond-forming reaction of activated aryl halides with primary fluoroalkyl alcohols is reported. BrettPhos ligand (L1) can alter the mechanistic pathway of reductive elimination from nucleophile to nucleophile (see scheme; Rf=–(CF2)nCF3; R=electron-releasing groups (ERGs) at o-, m- and p-positions, -neutral, and electron-withdrawing groups at o- and m-positions; EWG=electron-withdrawing group).

  5. Unprecedented 1,14-seco-Crotofolanes from Croton insularis: Oxidative Cleavage of Crotofolin C by a Putative Homo-Baeyer–Villiger Rearrangement

    Dr. Lidiya A. Maslovskaya, Dr. Andrei I. Savchenko, Carly J. Pierce, Dr. Victoria A. Gordon, Dr. Paul W. Reddell, Prof. Peter G. Parsons and Prof. Craig M. Williams

    Article first published online: 18 SEP 2014 | DOI: 10.1002/chem.201404250

    Structure elucidation: EBC-162, isolated from Croton insularis in northern Australia, was structurally affirmed as crotofolin C. Oxidation products of crotofolinC, EBC-233 and EBC-300, present the first crotofolane endoperoxides and an addition to the class of 1,14-seco-crotofolanes. An unprecedented homo-Baeyer–Villiger rearrangement is contemplated as a possible biosynthetic pathway (see scheme).
