      The cover picture shows that benzene/2,2′-bipyridine-alternately incorporated amide polymers are driven by hydrophobicity to form two helical conformations both of which exhibit helicity bias. Switching between the two helical conformations can be tuned by the coordination of the 2,2′-bipyridine units to Ni2+ ions. More details are discussed in the article by Li et al. on page 678–682.

      An improved method for the preparation of pentafluoroethylating reagent pentafluoroethyl-substituted benziodoxole (BIX-C2F5) was described. Under mild conditions, BIX-C2F5 was able to react with β-ketoesters or aryl/heteroaryl boronic acids to generate pentafluoroethylated compounds in good yields.

      The 2,2′-bipyridine unit has been incorporated into an aromatic amide polymer to tune the backbone to form two helical conformations as a result of Ni2+ coordination.

    3. Novel Total Synthesis of Mansouramycin B (pages 683–688)

      Yi Zhang, Xiaoxin Shi, Tianzhuo Meng, Qiqi Fan and Xia Lu

      Version of Record online: 25 APR 2016 | DOI: 10.1002/cjoc.201600020

      A novel total synthesis of Mansouramycin B (1) was performed via 10 steps in 28% overall yield starting from the readily available and cheap salicylaldehyde. Two key steps of this total synthesis are noteworthy. The first one is base-promoted one-pot aerobic aromatization of N-tosyltetrahydroisoquinoline 6, and the second one is oxidation of 5-hydroxy-3-methyl-isoquinoline 8 with iodobenzene diacetate.

    4. Multicomponent Strategy for the Preparation of Pyrrolo[1,2-a]pyrimidine Derivatives under Catalyst-Free and Microwave Irradiation Conditions (pages 696–702)

      Zhan Xun, Xian Feng, Jianjun Wang, Daqing Shi and Zhibin Huang

      Version of Record online: 19 MAY 2016 | DOI: 10.1002/cjoc.201600142

      Thumbnail image of graphical abstract

      A simple and efficient one-pot procedure has been developed for the construction of pyrrolo[1,2-a]pyrimidines via the three-component domino reaction of 5-aminopyrazoles, acetylenedicarboxylates and malononitrile under catalyst-free, microwave irradiation conditions. The key step in this transformation is the N[BOND]N bond cleavage reaction of the 5-aminopyrazole substrate, which has been reported in this context for the first time in this study. The advantages of this protocol include readily available starting materials, short reaction times and good regioselectivity.

      A porous N-doped carbon has been fabricated through a convenient, economical, and scalable route without the assistance of any activation or template technique. The biomass derived porous carbon delivers high reversible capacity (505 mAh·g−1 at 0.1 C), excellent rate capability (190 mAh·g−1 at 10 C), suggesting that the as-obtained carbon can be a promising anode material for lithium ion batteries (LIBs).
