    Asymmetric Reduction of α-Amino Ketones with a KBH4 Solution Catalyzed by Chiral Lewis Acids

    Peng He, Haifeng Zheng, Prof. Dr. Xiaohua Liu, Xiangjin Lian, Dr. Lili Lin and Prof. Dr. Xiaoming Feng

    Article first published online: 15 SEP 2014 | DOI: 10.1002/chem.201404732

    An efficient reduction of α-amino ketones with potassium borohydride solution catalyzed by chiral N,N′-dioxide–metal complex catalysts was accomplished under mild reaction conditions for the first time. It provided a simple, convenient, and practical approach for obtaining synthetically important chiral β-amino alcohols in good to excellent yields and enantioselectivities (see scheme).

  2. Total Synthesis of the Anti-inflammatory and Pro-resolving Lipid Mediator MaR1n−3 DPA Utilizing an sp3–sp3 Negishi Cross-Coupling Reaction

    Jørn Eivind Tungen, Dr. Marius Aursnes, Dr. Jesmond Dalli, Dr. Hildur Arnardottir, Prof. Dr. Charles Nicholas Serhan and Prof. Dr. Trond Vidar Hansen

    Versatile and Sustainable Synthesis of Cyclic Imides from Dicarboxylic Acids and Amines by Nb2O5 as a Base-Tolerant Heterogeneous Lewis Acid Catalyst

    Md. Ayub Ali, Dr. S. M. A. Hakim Siddiki, Dr. Kenichi Kon, Prof. Junya Hasegawa and Dr. Ken-ichi Shimizu

    Article first published online: 15 SEP 2014 | DOI: 10.1002/chem.201404538

    Thumbnail image of graphical abstract

    A general catalytic method for the direct cyclic imide synthesis from dicarboxylic acids with amines or NH3 under mild conditions using a reusable Nb2O5 catalyst is reported (see scheme). The method is effective for the synthesis of some pharmaceutically or industrially important cyclic imides, including N-hydroxyphthalimide and unsubstituted cyclic imides.

  4. Rhodium(III)-Catalyzed N-Nitroso-Directed C[BOND]H Addition to Ethyl 2-Oxoacetate for Cycloaddition/Fragmentation Synthesis of Indazoles

    Dr. Jinsen Chen, Pei Chen, Chao Song and Prof. Dr. Jin Zhu

    Article first published online: 15 SEP 2014 | DOI: 10.1002/chem.201404506

    Go cyclo! Herein RhIII-catalyzed N-nitroso-directed C[BOND]H addition to ethyl 2-oxoacetate for the formal [2+2] cycloaddition/fragmentation synthesis of indazoles is reported (see scheme; Cp*=1,2,3,4,5-pentamethylcyclopentadienyl). The unique reactivity pattern identified herein emphasizes the importance of forward reactivity analysis in the development of useful C[BOND]H functionalization-based synthetic tools.

  5. Photoresponsive DNA Nanocapsule Having an Open/Close System for Capture and Release of Nanomaterials

    Tomohiro Takenaka, Prof. Dr. Masayuki Endo, Dr. Yuki Suzuki, Dr. Yangyang Yang, Tomoko Emura, Kumi Hidaka, Dr. Takayuki Kato, Dr. Tomoko Miyata, Prof. Dr. Keiichi Namba and Prof. Dr. Hiroshi Sugiyama

    Article first published online: 15 SEP 2014 | DOI: 10.1002/chem.201404757

    Thumbnail image of graphical abstract

    An open and shut case: A square bipyramidal DNA nanocapsule (NC) was designed to create a nanomaterial carrier. A photocontrollable open/close system and toehold system were introduced into the NC for capture and release of a gold nanoparticle (AuNP) by photoirradiation and strand displacement. The encapsulation and release of the AuNP was successfully carried out by opening of the NC and strand displacement.
