Tunable Preparation of α‐Aminoacyl Fluorides and α‐Fluoroamides via Base‐Induced Cascade Multiple‐Cleavage Processes from Bromodifluorohydrin Reagents and Amines

Advanced Synthesis &Catalysis, EarlyView.
A mild and versatile strategy enabling the divergent synthesis of α‐fluoroamides and α‐aminoacyl fluorides from 2‐bromo‐2,2‐difluoro alcohols and amines is developed. The reaction shows broad scope and operational simplicity. Mechanistic and density functional theory studies support the formation of a putative gem‐difluoroepoxide intermediate ...

Visible‐Light‐Promoted Dearomatization for The Construction of Imidazole Scaffolds

Advanced Synthesis &Catalysis, EarlyView.
Lighting up flat aromatics: a visible‐light photocatalytic dearomative acylation of imidazo[1,2‐a]pyridines using α‐keto acids as sustainable acyl radical precursors is reported, leading to dual fluorescent imidazoles. Dearomatization is a powerful strategy for constructing complex carbocycles and heterocycles, though it typically relies on harsh ...

One‐Pot Cascade Synthesis of Isoquinolinone‐Fused Quinoxalines Through Sequential Rh(III)/Pd(II) Catalysis

Advanced Synthesis &Catalysis, EarlyView.
A new one‐pot, dual catalytic strategy for the synthesis of polycyclic isoquinolinone‐fused quinoxalines from commercially available N‐(2‐acetamidophenyl)benzamides and 1,3‐diynes is reported. This transformation proceeds via Rh(III)/Pd(II)‐mediated sequential NH/CH activation/annulation. Detailed mechanistic studies elucidate the reaction pathway. A
