Autor: Tom G. Driver, Ragda Izar, Navendu Jana, Wrickban Mazumdar, Donald J. Wink, Russell L Ford, Tianning Deng

Publikováno v: Journal of the American Chemical Society. 142:4456-4463

A low-temperature, protecting-group-free oxidation of 2-substituted anilines has been developed to generate an electrophilic N-aryl nitrenoid intermediate that can engage in C-NAr bond formation to construct functionalized N-heterocycles. The exposur

Rh(2)(II)-Catalyzed Intermolecular N-Aryl Aziridination of Olefins using Nonactivated N-Atom Precursors

Autor: Tianning Deng, Tala Malo, Tom G. Driver, Yuki Yoshinaga, Wrickban Mazumdar, Pooja B. Patel, Dana Malo, Donald J. Wink

Publikováno v: J Am Chem Soc

The development of the first intermolecular Rh2(II)-catalyzed aziridination of olefins using anilines as nonactivated N atom precursors and an iodine(III) reagent as the stoichiometric oxidant is reported. This reaction requires the transfer of an N-

Rh2(II)-Catalyzed Ring Expansion of Cyclobutanol-Substituted Aryl Azides To Access Medium-Sized N-Heterocycles

Autor: Tom G. Driver, Wrickban Mazumdar, Bryant T. Thurman, Donald J. Wink, Navendu Jana

Publikováno v: Journal of the American Chemical Society. 139:5031-5034

A new reactivity pattern of Rh2(II)-N-arylnitrenes was discovered that facilitates the synthesis of medium-sized N-heterocycles from ortho-cyclobutanol-substituted aryl azides. The key ring-expansion step of the catalytic cycle is both chemoselective
