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

Proton‐Coupled Electron Transfer Processes in the Decarboxylative Synthesis of C‐4 Substituted Chroman‐2‐Ones

Advanced Synthesis &Catalysis, EarlyView.
This research presents a new mild photocatalytic method enables C‐4 alkylation of chroman‐2‐one derivatives with primary alkyl radicals. This radicals are generated via oxidative PCET process. Developed approach offers broad substrate scope, scalability under photo‐flow conditions, and mechanistic evidence supports a decarboxylation pathway under polar

Cu(I)‐Catalyzed Interrupted Cycloaddition Between Azides, Ag(I)‐Acetylides, and Diorganoyl Dichalcogenides

Advanced Synthesis &Catalysis, EarlyView.
Unleashing the power of Ag(I)‐acetylides with LiCl/dimethyl sulfoxide (DMSO). The LiCl/DMSO mixture have an unexplored ability to dramatically increase the solubility of Ag(I)‐acetylides regardless of their molecular structure, which is explored to achieve high chemoselectivity in the Cu(I)‐catalyzed interrupted cycloaddition between organic azides, Ag(

Polylactic Acid (PLA), Polycaprolactone (PCL), and Chitosan: the Biodegradable Transition in Medical Waste Management

Advanced Sustainable Systems, EarlyView.
The shift to biodegradable materials in healthcare promises reduced plastic pollution, but their production, adoption, and long‐term impacts remain complex. Integrating lifecycle insights with global policy coordination is essential for meaningful environmental gains. Abstract The COVID‐19 pandemic sharply increased medical waste, intensifying concerns
