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

Cooperative Photocatalysis of 9,10‐Phenanthrenequinone and Sn(OTf)2 for Direct Mannich Reaction of Ethers via Hydrogen Atom Transfer Pathway

Advanced Synthesis &Catalysis, EarlyView.
A dual photocatalytic system of o‐PQ and Sn(OTf)2 enables visible light‐induced Mannich‐type addition of ethers to nitrones via Csp³–H activation. This oxidant‐free method offers broad scope and good yields. Mechanistic studies suggest that a photoexcited o‐PQ–Sn(II) complex mediates hydrogen atom transfer to form α‐oxy radicals for nitrone addition. A

Recent Advances in Ene Reactions with Carbon Enophiles

Advanced Synthesis &Catalysis, EarlyView.
Recent advances in the classical intra‐ and intermolecular ene nexus with carbon enophiles (alkenes, alkynes, arynes, and allenes) show a considerable increase in structural complexity and an enormous potential for functional applications in polymer science.

A Mild and Efficient Iridium‐Catalyzed Method for Aldimine Hydrogenation

Advanced Synthesis &Catalysis, EarlyView.
A mild, efficient, and broadly applicable iridium‐catalyzed method for aldimine hydrogenation, facilitating access to an array of corresponding amine products in high isolated yields is reported. The developed methodology employs a bidentate iridium‐N‐heterocyclic carbene‐phosphine complex for use at low catalyst loadings, and proceeds under an ...
