Two-Step Transesterification of Phosphates, Phosphorothioates, and Phosphonates with a Binaphthyl Group for the Synthesis of P-Chirogenic Phosphates and Phosphonates

Autor: Toshiaki Murai, Chikako Endo, Yurika Inoue, Toshifumi Maruyama, Mao Minoura

Publikováno v: Synthesis. 55:934-944

Two-step transesterification of four-coordinate pentavalent organophosphorus compounds with a binaphthyl group has been studied in detail. The first step involves transfer of the axial chirality of a hydroxybinaphthyl group to the central chirality

5-N-Arylaminothiazoles with pyridyl groups and their first-row transition metal complexes: synthesis, photophysical properties, and Zn sensing

Autor: Khurnia Krisna Puji Pamungkas, Toshifumi Maruyama, Toshiaki Murai

Publikováno v: RSC Advances. 12:14698-14706

A series of 5-N-arylaminothiazoles were used to form isolable nickel complexes, whose structure was disclosed by X-ray structure analysis, and were used for the detection of zinc halides in solutions with the enhancement of emission properties.

N-Alkenylation of hydroxamic acid derivatives with ethynyl benziodoxolone to synthesize cis-enamides through vinyl benziodoxolones

Autor: Norihiro Tada, Akichika Itoh, Daisuke Shimbo, Toshifumi Maruyama

Publikováno v: Organic & Biomolecular Chemistry. 19:2442-2447

The stereoselective synthesis of cis-β-N-alkoxyamidevinyl benziodoxolones (cis-β-N-RO-amide-VBXs) from O-alkyl hydroxamic acids in the presence of an ethynyl benziodoxolone-acetonitrile complex (EBX-MeCN) is reported herein. The reaction was perfor

Chemoselective and Stereoselective Alcoholysis of Binaphthyl Phosphonothioates: Straightforward Access to Both Stereoisomers of Biologically Relevant P-Stereogenic Phosphonothioates

Autor: Yuuki Maekawa, Toshifumi Maruyama, Mao Minoura, Kazuma Kuwabara, Toshiaki Murai

Publikováno v: The Journal of Organic Chemistry. 85:14446-14455

P-Stereogenic phosphonothioates have attracted great attention due to their potent biological activities as analogues of phosphoric acids and phosphorothioates. We demonstrate here straightforward access to P-stereogenic phosphonothioates through the

Boron complexes of thiazole-bridged 1,5-bidentate nitrogen ligands: synthesis and acid-responsive photophysical properties

Autor: Toshifumi Maruyama, Khurnia Krisna Puji Pamungkas, Toshiaki Murai

Publikováno v: Organicbiomolecular chemistry. 19(31)

Boron complexes of 1,5-bidentate nitrogen ligands with a thiazole linker were synthesized by the halogenation of 5-H thiazoles followed by Buchwald–Hartwig amination and complexation with BF3·Et2O. These boron complexes showed a large Stokes shift

Synthesis, Characterization, and Reactivity of an Ethynyl Benziodoxolone (EBX)–Acetonitrile Complex

Autor: Daisuke Shimbo, Norihiro Tada, Akichika Itoh, Masaharu Yudasaka, Toshifumi Maruyama

Publikováno v: Organic Letters. 21:1098-1102

The synthesis of a crystalline ethynyl-1,2-benziodoxol-3(1 H)-one (EBX)-acetonitrile complex is described. EBX has been widely used as an active species for a variety of reactions; however, its high instability has so far prevented its isolation. The
