Nucleophilic Reactions of Cyclobutenones and the Related 4,4‐Dichlorocyclobutenone Derivatives
European Journal of Organic Chemistry, EarlyView.Cyclobutenone derivates and their 4,4‐dichloro counterparts have an uninterrupted attention as useful synthons in the synthesis of complex organic molecules. Their nucleophilic reactions remain underexplored. This review brings attention to these reactions, whose outcome is not straightforward.

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 ...

Modular Synthesis of Di‐ and Triazadibenzoazulenes by a Cross‐Coupling/Cycloisomerization Strategy
European Journal of Organic Chemistry, EarlyView.Two series of regioisomeric di‐ and triazadibenzoazulenes were prepared from dihalogenated imidazo[1,2‐a]pyridines and imidazo[1,2‐a]pyrazines. Imidazo[1,2‐a]pyridines and imidazo[1,2‐a]pyrazines are important nitrogen‐containing heterocycles with applications in medicinal and materials chemistry.

European Journal of Organic Chemistry, EarlyView.An efficient gold‐catalyzed intramolecular cyclization of indole‐tethered alkynes using AgNTf2 as an additive has been developed, which provides bioactive exocyclic alkenyl tetrahydrocarbazoles with up to 85% yield. Control experiments and DFT studies indicate that the reaction proceeds via a 6‐exo‐dig cyclization pathway, with gold acetylide complexes
