Remote electronic effect on the N-heterocyclic carbene-catalyzed asymmetric intramolecular Stetter reaction and structural revision of products

Autor: Tsubasa Inokuma, Kohei Iritani, Yuki Takahara, Chunzhao Sun, Yousuke Yamaoka, Satoru Kuwano, Ken-ichi Yamada

Publikováno v: Chemical Communications. 59:5375-5378

The remote electron-withdrawing substituents on the chiral N-heterocyclic carbene enhanced rate and enantioselectivity in the asymmetric intramolecular Stetter reaction. The absolute configurations of the products were revised by X-ray diffraction.

Efficient oxyselenation and aminoselenation utilizing a selenenyl iodide based on the characteristic thermodynamics of its reaction with olefins

Autor: Satoru Kuwano, Erika Takahashi, Jun Kikushima, Shohei Sase, Kei Goto

Publikováno v: New Journal of Chemistry. 47:9569-9574

Using an isolable selenenyl iodide, the characteristic thermodynamics of selenenyl iodide addition to olefins were elucidated and applied to develop the efficient selenofunctionalization of olefins with external oxygen or nitrogen nucleophiles.

Enhanced Molecular Recognition through Substrate–Additive Complex Formation in N-Heterocyclic-Carbene-Catalyzed Kinetic Resolution of α-Hydroxythioamides

Autor: Yinli Wang, Akiho Yamauchi, Keiji Hashimoto, Tatsuya Fujiwara, Tsubasa Inokuma, Yuta Mitani, Koichi Ute, Satoru Kuwano, Yousuke Yamaoka, Kiyosei Takasu, Ken-ichi Yamada

Publikováno v: ACS Catalysis. 12(10):6100-6107

We describe a new way of understanding enhanced molecular recognition through substrate–additive complex formation and the development of the first catalytic kinetic resolution of α-hydroxythioamides, which are versatile synthetic building blocks,

Late-Stage Functionalization of the Periphery of Oligophenylene Dendrimers with Various Arene Units via Fourfold C–H Borylation

Autor: Satoru Kuwano, Ryosuke Masuda, Kei Goto

Publikováno v: The Journal of Organic Chemistry. 86:14433-14443

Late-stage functionalization of the periphery of oligophenylene dendrimers was efficiently achieved via site-selective C-H activation of a preconstructed, readily accessible dendron. By fourfold iridium-catalyzed C-H borylation followed by Suzuki-Miy

A Hypervalent Cyclic Dibenzoiodolium Salt as a Halogen‐Bond‐Donor Catalyst for the [4+2] Cycloaddition of 2‐Alkenylindoles

Autor: Yuki Nishida, Takumi Suzuki, Satoru Kuwano, Takayoshi Arai, Yuri Takagi, Emi Amma, Ryoya Tajima

Publikováno v: ChemPlusChem. 86:741-744

A stable, hypervalent cyclic dibenzoiodolium salt acted as a strong halogen bonding (XB)-donor catalyst for [4+2] cycloaddition of 2-alkenylindoles, and not as an oxidizing agent. The cross-[4+2] cycloaddition of 2-vinylindoles with 2-alkenylindoles
