For the past two years, AsianJOC has brought you excellent research for free. This trial period is now over. Please consider a subscription or recommend the journal to your librarian. AsianJOC is owned by ACES, a consortium of Asian chemical societies. The individual societies will benefit from the revenues and so will the communities they serve.

There will be an updated version of our iPad app in the App Store in a few days. It fully supports subscriptions and will also work on the iPhone.

  1. Domino Knoevenagel Condensation/Aza-Ene Addition/N-Cyclization Route to Functionalized Imidazo[1,2-a]pyridines and Pyrido[1,2-a]pyrimidines

    Sathiyamoorthi Sivakumar and Raju Ranjith Kumar

    Article first published online: 23 JUL 2014 | DOI: 10.1002/ajoc.201402100

    One-pot wonder! The syntheses of imidazo[1,2-a]pyridines and pyrido[1,2-a]pyrimidines were carried out by using a one-pot three-component protocol. The reaction proceeds in a single step through a domino Knoevenagel condensation/aza-ene addition/imine–enamine tautomerization/chemoselective N-cyclization sequence of reactions (In=indolyl).

  2. Application of Regio- and Stereoselective Functional Group Transformations of Chiral Aziridine-2-carboxylates

    Prof. Dr. Hyun-Joon Ha, Jae-Hoon Jung and Prof. Dr. Won Koo Lee

    Article first published online: 23 JUL 2014 | DOI: 10.1002/ajoc.201402098

    Boxing clever: This Focus Review highlights the chemistry of chiral aziridine-2-carboxylates as building blocks based on regio- and stereoselective functional group transformations of the carboxylate group and aziridine ring. This chemistry is exemplified by the efficient and highly stereoselective synthesis of many biologically important amines, including several natural products.

  3. Upward Trend in Catalytic Efficiency of Rare-Earth Triflate Catalysts in Friedel–Crafts Aromatic Sulfonylation Reactions

    Vo Thu An Nguyen, Prof. Dr. Fritz Duus and Prof. Dr. Thach Ngoc Le

    Article first published online: 22 JUL 2014 | DOI: 10.1002/ajoc.201402067

    Going up! The upward trend in efficiency of lanthanide (Ln) triflates in catalyzing aromatic sulfonylation reaction correlates with the lanthanide sequence in the periodic table. Various related physical properties of lanthanide ions were found to have some influence on the catalytic activity.

  4. One-Pot Copper-Catalyzed Aerobic Decarboxylative Coupling of Phenylacetic Acids with o-Aminobenzenes and Dioxygen as the Oxidant Leading to Benzoxazoles and Benzothiazoles

    Daoshan Yang, Kelu Yan, Wei Wei, Laijin Tian, Yuanyuan Shuai, Ruixia Li, Jinmao You and Prof. Hua Wang

    Article first published online: 22 JUL 2014 | DOI: 10.1002/ajoc.201402085

    A fair cop: A copper-catalyzed synthesis of benzoxazole and benzothiazole derivatives via cascade reactions of substituted o-aminobenzenes with phenylacetic acids under dixoygen has been developed. The method is practical and the starting materials are readily available. These advantages provide an opportunity for the construction of diverse and useful benzoxazole and benzothiazole motifs within organic, medicinal, and materials chemistry

  5. A Ruthenium-Based Light-Harvesting Antenna Bearing an Anthracene Moiety in Dye-Sensitized Solar Cells

    Dr. Georgios C. Vougioukalakis, Dr. Maria Konstantakou, Dr. Eleftherios K. Pefkianakis, Antonios N. Kabanakis, Dr. Thomas Stergiopoulos, Dr. Athanassios G. Kontos, Dr. Aikaterini K. Andreopoulou, Prof. Dr. Joannis K. Kallitsis and Dr. Polycarpos Falaras

    Article first published online: 14 JUL 2014 | DOI: 10.1002/ajoc.201402096

    Ru-thlessly efficient: A heteroleptic ruthenium-based light-harvesting antenna coordinated with a phenylanthracene-substituted terpyridine, a bipyridine, and a NCS ligand was synthesized. TiO2 films sensitized by this photosensitizer were studied through various techniques. The photosensitizer was evaluated in I/I3-based liquid electrolyte dye-sensitized solar cells, affording overall power conversion efficiencies up to 3.75 %.
