Synthesis of γ-lactams via Ru(II)–Pheox-catalyzed regioselective intramolecular Csp3–H insertion of diazoacetamides
Autor: Takuji Fujii, Huong Dang Thi Thu, Seiji Iwasa
Publikováno v: Tetrahedron Letters. 61:152276
Herein, γ-lactam derivatives are obtained in high yield via highly regioselective intramolecular Csp3–H insertion reactions of α-diazoacetamides catalyzed by a rac-Ru(II)–Pheox complex. The catalytic system is applicable to a wide range of diaz

Highly enantioselective synthesis of trifluoromethyl cyclopropanes by using Ru(ii)-Pheox catalysts
Autor: Takuji Fujii, Soda Chanthamath, Manato Kotozaki, Seiji Iwasa, Kazutaka Shibatomi
Publikováno v: Chemical communications (Cambridge, England). 54(40)
An asymmetric synthesis of various trifluoromethyl cyclopropanes from olefins, such as vinyl ferrocene, vinyl ethers, vinyl amines, vinyl carbamates and dienes, was achieved by using Ru(II)–Pheox catalysts. This catalytic system can function at a l

Modular Synthesis of Benzocyclobutenes via Pd(II)-Catalyzed Oxidative [2+2] Annulation of Arylboronic Acids with Alkenes
Autor: Takuji Fujii, Simone Gallarati, Clémence Corminboeuf, Qian Wang, Jieping Zhu
Publikováno v: Journal of American Chemical Society
Benzocyclobutenes (BCBs) are highly valuable compounds in organic synthesis, medicinal chemistry, and materials science. However, catalytic modular synthesis of functionalized BCBs from easily accessible starting materials remains limited. We report
