      An unprecedented protocol has been developed for the efficiend synthesis of substituted tetrahydropyrans via a bismuth-promoted Prins cyclization of imines with homoallyl alcohols. In the presence of 40 mol% BiCl3, a wide variety of imines react smoothly with homoallyl alcohols at room temperature to give the corresponding 4-chlorotetrahydropyran derivatives in good to excellent yields.

    1. Controllable Fabrication of Various Supramolecular Nanostructures Based on Nonamphiphilic Azobenzene Derivatives and Pillar[6]arene

      Shan Qin, Shuhan Xiong, Yang Han, Xiao-Yu Hu and Leyong Wang

      Article first published online: 8 OCT 2014 | DOI: 10.1002/cjoc.201400508

      Thumbnail image of graphical abstract

      Various novel types of supramolecular nanostructures formed by nonamphiphilic azobenzene derivatives, G1 or G2 have been successful fabricated, where G2 is structurally similar with G1 but an extra phenoxy group is connected with the azobenzene motif. Micellar structures can be obtained from the self-assembly of G1, which further transformed to large-sized spindle structures; while nanorods can be initially formed by G2, which will gradually aggregate to form layered structures with much larger size. Moreover, it is found that upon addition of WP6, which can form inclusion-complex with G1 or G2, separately, the nonamphiphilic G1 and G2 thus converse to supramolecular amphiphiles WP6G1 and WP6G2, respectively. Consequently, both of the above WP6G1 and WP6G2 complexes can further assemble to form supramolecular binary vesicles, which will gradually transform to nanotubes (WP6G1) or well-ordered nanosheets (WP6G2).

    2. A Novel Efficient Ligand in Anionic Polymerization at Elevated Temperature

      Bo Chen, Jiming Wang, Minze Shu, Bin Zou, Yong Guan and Anna Zheng

      Article first published online: 15 SEP 2014 | DOI: 10.1002/cjoc.201400351

      It was confirmed that lithium phenoxide could associate with the active center to block the inserting tunnels in anionic polymerization. With lithium phenoxide, the stability of n-BuLi in THF at 0°C was greatly improved. Due to the steric hindrance effect, the lithium phenoxide could diminish the polymerization rate in the polymerization of both St and MMA. In the polymerization of Ip with lithium phenoxide, it was found that the formations of 1,2- and 1,4-configurations were impeded, while the formation of 3,4-configuration was promoted.
