Nitrate Reduction for Deaminative Suzuki–Miyaura Coupling of Anilines

open access: yesAngewandte Chemie, EarlyView.
We present a one‐step deaminative Suzuki–Miyaura‐type coupling of anilines via fleeting diazonium intermediate with nitrate and bisulfite as the reagents. This represents the first application of the nitrate reduction strategy in transition metal catalysis of diazonium chemistry.

Interrupted Barton–Zard Reaction/Friedel–Crafts Alkylation Telescoped Reaction for the Synthesis of Pyrrolo[3,4‐b]indole Cores

open access: yesAsian Journal of Organic Chemistry, EarlyView.
An interrupted Barton–Zard reaction/Friedel–Crafts alkylation telescoped reaction provides aryl‐substituted pyrrolo[3,4‐b] cores in moderate‐to‐good yields as mostly single diastereomers. The reaction is tolerant of a wide range of electron‐deficient indoles and (hetero)aromatic nucleophiles, offering a modular approach for the synthesis of multi ...

β‐Quaternary α‐Amino Acids via Iridium‐Catalyzed Branched and Enantioselective Hydroalkylation of 1,1‐Disubstituted Styrenes

open access: yesAngewandte Chemie, EarlyView.
A cationic Ir(I)‐complex modified with the chiral diphosphine DM‐SEGPHOS mediates the enantioselective hydroalkylation of diverse α‐substituted styrenes with N‐aryl glycine derivatives. The products are readily advanced to β‐quaternary α‐amino acids that are inaccessible or cumbersome to access by other means. Abstract A cationic Ir(I)‐complex modified
