Cobalt‐Catalyzed C(sp3)H Carbonylation Enabled by Mo(CO)6

European Journal of Organic Chemistry, EarlyView.
Cobalt‐catalyzed carbonylative C(sp3)H cyclization of aliphatic amides using Mo(CO)6 as a solid CO surrogate enables efficient access to substituted succinimides under operationally simple conditions. The carbonylation of unactivated C(sp3)H bonds represents an attractive strategy for the synthesis of valuable carbonyl‐containing compounds.

Synthesis of Naphthoquinones by Pd‐Catalyzed Heck–Matsuda Arylation of Lapachol

European Journal of Organic Chemistry, EarlyView.
Direct Heck–Matsuda arylation of lapachol enables the efficient synthesis of diverse naphthoquinones under homogeneous and heterogeneous palladium catalysis. The methodology features broad substrate scope, gram‐scale applicability, and provides a practical platform for quinone diversification.

Synthesis of Cysteine–Fluorophore Conjugates by Visible‐Light‐Promoted Thiol–Ene Coupling Using Organic Photocatalysts

European Journal of Organic Chemistry, EarlyView.
Cysteine–fluorophore conjugates were efficiently prepared through a visible‐light‐driven thiol–ene approach employing solely organic photocatalysts. The reaction proceeds under mild, metal‐free conditions. The fluorophore scope includes mono‐ and dialkene‐functionalized naphthalene, naphthalimide, and aromatic diimide derivatives.

FeIII‐Mediated Synthesis of Azaspirodienones via Ipso‐Radical Cyclization of Ugi–4CR Adducts

European Journal of Organic Chemistry, EarlyView.
An efficient two‐step protocol for the synthesis of azaspirodienones via Fe‐mediated ipso‐radical cyclization of Ugi adducts has been developed. This methodology provides rapid access to these privileged spirocyclic architectures under mild conditions, offering a practical and versatile approach to generating structurally complex molecules with ...
