A Chiral N-Tetrafluoroiodobenzyl-N-sulfonyl Aminomethylpyrrolidine Catalyst for the Enantioselective Michael/Hemiaminal Formation Cascade Reaction of α,β-Unsaturated Iminoindoles with Aldehydes

Autor: Katsuhiko Moriyama, Yukari Oka, Tatsuo Kaiho

Publikováno v: Synlett. 33:1763-1769

A chiral N-2,3,4,5-tetrafluoro-6-iodobenzyl-N-sulfonyl aminomethylpyrrolidine tetrafluoroacetic acid salt was designed as an iodinated enamine organocatalyst for the enantioselective Michael/hemiaminal formation cascade reaction of α,β-unsatu

Chemoselective Reduction ofα,β-Unsaturated Carbonyl and Carboxylic Compounds by Hydrogen Iodide

Autor: Shoji Matsumoto, Tatsuo Kaiho, Yasuhiko Otani, Motohiro Akazome, Hayato Marumoto

Publikováno v: Bulletin of the Chemical Society of Japan. 94:590-599

The selective reduction of α,β-unsaturated carbonyl compounds was achieved to produce saturated carbonyl compounds with aqueous HI solution. The introduction of an aryl group at an α or β position ...

The diiodomethyl-sulfonyl moiety: an unexplored halogen bond-donor motif

Autor: Maurizio Ursini, Pierangelo Metrangolo, Giancarlo Terraneo, Tullio Pilati, Tatsuo Kaiho, Valentina Dichiarante, Giuseppe Resnati

Publikováno v: Chemical communications (Cambridge, England). 55(29)

Herein, we report the crystal structures of the antimicrobial agent diiodomethyl-p-tolylsulfone and of three halogen bonded co-crystals demonstrating that the bioactive moiety -SO2CHI2 can function as a quite effective halogen bond based motif in the

Rapid Synthesis of D-A'-π-A Dyes through a One-Pot Three-Component Suzuki-Miyaura Coupling and an Evaluation of their Photovoltaic Properties for Use in Dye-Sensitized Solar Cells

Autor: Yuji Wada, Takashi Takahashi, Shinichiro Fuse, Masato M. Maitani, Yuhei Ogomi, Shunsuke Irie, Hisashi Masui, Hiroshi Tanaka, Shuzi Hayase, Tatsuo Kaiho

Publikováno v: Chemistry - A European Journal. 22(No. 7):2507-2514

Twenty-four D-A′–π-A dyes were rapidly synthesized through a one-pot three-component Suzuki–Miyaura coupling reaction, which was assisted by microwave irradiation. We measured the absorption spectra, electrochemical properties, and solar-cell

Synthesis and Evaluation of Thiophene-Based Organic Dyes Containing a Rigid and Nonplanar Donor with Secondary Electron Donors for Use in Dye-Sensitized Solar Cells

Autor: Hiroshi Tanaka, Yuji Wada, Tatsuo Kaiho, Shinichiro Fuse, Takashi Takahashi, Masato M. Maitani, Ryota Takahashi

Publikováno v: European Journal of Organic Chemistry. 2016:508-517

We demonstrate herein the divergent synthesis of six dyes containing our originally developed rigid and nonplanar donor with three different secondary electron donors (SEDs), namely thiophene, 4-methoxybenzene, and diphenylethene. Evaluation of the p
