Rapid Access to an Enantioenriched Spiro Bisindole Directly from Indole and Acetone
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‐

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.

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 ...

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
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.
