Reactions of the allyltin trichloride 45 generated from (4S)-4-benzyloxypent-2-enyl(tributyl)stannane 1 with imines prepared from glyoxylates proceed with useful levels of 1,5-stereocontrol in favour of (4E)-2,6-anti-2-(alkylamino)-6-benzyloxyhept-4-enoates 49. This stereoselectivity, controlled by the chirality of the stannane, dominates over any intrinsic stereochemical
A six-step one-pot reaction was designed for synthesizing homodimeric 7-phenylindolo[3,2-a]carbazoles from 1H-indoles and β-nitrostyrenes, in the presence of SnCl(2)·2H(2)O. The reactions proceeded under very mild conditions and the desired heterocycles were obtained in moderate to good yields. An unprecedented mechanism

The synthesis of 2-(1H-pyrrolo[2,3-b]pyridin-3-yl)quinolines by a SnCl(2)-catalyzed multicomponent reaction has been described. The reaction proceeds chemo- and regioselectively in an atom-economic way, generating a library of 24 quinoline derivatives.
The anionic speciation of chlorostannate(II) ionic liquids, prepared by mixing 1-alkyl-3-methylimidazolium chloride and tin(II) chloride in various molar ratios, χ(SnCl2), was investigated in both solid and liquid states. The room temperature ionic liquids were investigated by (119)Sn NMR spectroscopy, X-ray
The Zn-Sn nanoparticles/multiwall carbon nanotubes (Zn-SnNPs/MWNTs) nanocomposite film was prepared by electrodeposition of ZnCl(2) and SnCl(2) on MWNTs simultaneously in Ethaline ionic liquids. Then, based on immobilizing hemoglobin (Hb) within a novel Zn-SnNPs/MWNTs nanocomposite film (Hb/Zn-SnNPs/MWNTs), a novel hydrogen peroxide
