Formation of Bicyclic Skeletons by Aerobic, Manganese‐Mediated Cyclization of β‐Oxoesters

European Journal of Organic Chemistry, EarlyView.
Manganese(III) promotes aerobic radical cyclization reactions of β‐oxoesters with an ω‐alkenyl side chain at the β’‐position to give bicyclic products with a 1,4‐dicarbonyl structure. Bicyclic perhydro‐pentalene, ‐indene, and ‐azulene, as well as decaline skeletons were accessed by aerobic manganese(III)‐mediated radical cyclizations of cyclic β ...

Stereoselective Construction of Benzo‐Fused Tetrahydropyrrole Thiazines From Saccharin

European Journal of Organic Chemistry, EarlyView.
Saccharin was used as a template to construct a series of 10a‐substituted, benzo‐fused, pyrrolo thiazinone dioxides. Thereafter, diastereo‐divergent 10‐keto reduction gave either diastereomeric alcohol in a process that did not rely on the substituent at 10a's identity.

Diastereoselective Synthesis of Highly Substituted Methylene Cyclobutanes by Pd Catalysis

European Journal of Organic Chemistry, EarlyView.
A chemo‐ and diastereoselective palladium‐catalyzed intramolecular coupling/cyclization of borylated 1,5‐dienes, readily accessible by allene allylboration, with iodoarenes enables the synthesis of highly substituted methylene cyclobutanes. The method exhibits broad scope, high functional group tolerance, and complete enantiospecificity.

From Molecules to Materials: The Role of Halogen Bonds in Electron Donor–Acceptor Complex Mediated Organic Synthesis

European Journal of Organic Chemistry, EarlyView.
This Concept highlights recent advances in organic synthesis based on electron donor–acceptor (EDA) complex photochemistry, with emphasis on halogen bonding. Halides play a dual role as key components of this noncovalent interaction, and as reactivity‐enabling leaving groups.

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

European Journal of Organic Chemistry, EarlyView.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

Hydroformylation of Olefins With Paraformaldehyde Catalyzed by a Rhodium(I)/Diphosphine/Diphosphoramidite System

European Journal of Organic Chemistry, EarlyView.
A new dual‐ligand rhodium catalytic system based on [RhCl(cod)]2, BINAP or BIPHEP, and a diphosphoramidite ligand enables the hydroformylation of olefins using paraformaldehyde as a syngas surrogate. The system efficiently converts vinyl arenes, alkyl olefins, cyclopentene, and allyl acetate with high activity and regioselectivity.
