  1. Short Convergent Synthesis of the Mycolactone Core Through Lithiation–Borylation Homologations

    Christopher A. Brown and Prof. Dr. Varinder K. Aggarwal

    Article first published online: 1 SEP 2015 | DOI: 10.1002/chem.201503122

    Rapid complexity: Using iterative lithiation–borylation homologations, the mycolactone toxin core has been synthesized in 13 steps and 17 % overall yield. The rapid build-up of molecular complexity, high convergence and high stereoselectivity are noteworthy features of the synthesis (see scheme; TBS=tert-butylsilyl, pin=pinacolato, Cb=N,N-diisopropylcarbamoyl, sp=sparteine).

  2. Photoinduced Aminocarbonylation of Aryl Iodides

    Dr. Takuji Kawamoto, Aoi Sato and Prof. Dr. Ilhyong Ryu

    Article first published online: 1 SEP 2015 | DOI: 10.1002/chem.201503164

    Catalyst-free aminocarbonylation of aryl iodides with CO and amines proceeds with broad functional-group tolerance including heteroaromatic amides. This novel aminocarbonylation simply uses photoirradiation to effect radical initiation. A chain mechanism is proposed, involving electron transfer from zwitterionic radical intermediates generated by nucleophilic attack of amines to aroyl radicals as the key.

  3. Organic Dyes with Well-Defined Structures for Highly Efficient Dye-Sensitised Solar Cells Based on a Cobalt Electrolyte

    Dr. Kang Deuk Seo, In Tack Choi and Prof. Hwan Kyu Kim

    Article first published online: 1 SEP 2015 | DOI: 10.1002/chem.201502289

    How long is the ideal bridge? The photovoltaic performance of DSSCs based on organic dyes with oligothiophenes depends on the molecular structure of the dyes in terms of the length of the π-bridge. The organic dyes, consist of bisdimethylfluoreneyl amino groups with a dialkoxyphenyl unit as the electron donor and a cyanoacrylic acid group as an anchoring group, and are connected to oligothiophenes, fused thiophenes and electron-withdrawing benzothiadiazoles as π-bridging units (an example is shown here).

  4. Chlorination-Promoted Skeletal-Cage Transformations of C88 Fullerene by C2 Losses and a C[BOND]C Bond Rotation

    Prof. Dr. Shangfeng Yang, Dr. Tao Wei, Dr. Kerstin Scheurell, Prof. Dr. Erhard Kemnitz and Prof. Dr. Sergey I. Troyanov

    Article first published online: 1 SEP 2015 | DOI: 10.1002/chem.201501549

    Chlorination of C88 fullerene results in skeletal-cage transformations that include C2 losses and a Stone–Wales rearrangement. Five nonclassical fullerene chlorides, C86Cl24/26 and C84Cl26, have been isolated, containing one and two heptagons in the carbon cages. All compounds are included in the branched transformation pathway (see scheme; cage heptagons and pentagons are shown in blue and red, respectively).

  5. Synthesis of Aryl Tri- and Difluoromethyl Thioethers via a C[BOND]H-Thiocyanation/Fluoroalkylation Cascade

    Dr. Kévin Jouvin, Christian Matheis and Prof. Dr. Lukas J. Goossen

    Article first published online: 1 SEP 2015 | DOI: 10.1002/chem.201502914

    Perfectly formed: An AlCl3-catalyzed C[BOND]H thiocyanation was combined with a Langlois-type trifluoromethylation to afford aryl trifluoromethyl thioethers directly from arenes, N-thiocyanatosuccinimide and TMS-CF3 (see scheme). An analogous combination of the thiocyanation with a copper-mediated difluoromethylation gives access to aryl difluoromethyl thioethers. The sulfur and fluoroalkyl groups originate from different sources, so that preformed fluoroalkylthiolation reagents are avoided.
