Rapid Access to an Enantioenriched Spiro Bisindole Directly from Indole and Acetone
Angewandte Chemie, EarlyView.A catalytic enantioselective one‐pot “self‐assembly” strategy was developed for the exceedingly convenient access to a spiro bisindole directly from indole and acetone. The obtained enantiopure C2‐symmetric bisindole showed exceptional performance as a chiral backbone of diverse effective catalysts or ligands. Abstract Disclosed here is a “one‐pot self‐

Angewandte Chemie, EarlyView.This work pioneers a solvent‐free mechanochemical borrowing hydrogen (BH) strategy for the rapid and efficient N‐alkylation of amines and heterocycles. By removing harsh conditions and toxic reagents while employing a simple Ru catalyst, this approach redefines BH as a cleaner, more versatile, and sustainable platform for synthetic chemistry.

Angewandte Chemie, EarlyView.A highly enantioselective iridium‐catalyzed hydroarylation of allene‐tethered pyrroles and indoles that provides access to relevant heterocyclic systems bearing vinyl‐substituted 3ry or 4ry stereocenters is reported. Its synthetic potential was exemplified with a very short, highly enantioselective formal synthesis of (+)‐Rhazinilam, whereas DFT ...

Angewandte Chemie, EarlyView.Herein, we report the use of bis(trimethylaluminum)‐1,4‐diazabicyclo[2.2.2]octane (DABAl‐Me3) as practical source of radicals for the introduction of valuable methyl groups to aryl bromides via a Nickel/metallaphotocatalytic cross coupling strategy.

Nickel‐Catalyzed Suzuki–Miyaura Cross‐Coupling Reaction of Aliphatic Alcohol Derivatives
Angewandte Chemie, EarlyView.A nickel‐catalyzed Suzuki–Miyaura coupling reaction of aliphatic mesylates is reported. This reaction provides a strategy for late‐stage functionalization of bioactive compounds that have high F(sp3). Preliminary mechanistic experiments confirm a stereoablative reaction outcome, consistent with alkyl radical intermediates.
