Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Emergent Atropisomerism Through Diels–Alder Reactions of Vinylallenes

European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
Cycloaddition‐induced geometric reorganization transforms achiral vinylallenes into atropisomeric styrenes. Conformational flexibility governs atropisomerization barriers, thermodynamic preferences, and configurational stability. Atropisomeric styrenes remain comparatively underdeveloped because configurational stability about the C(sp2)C(sp2) bond is

Cyclopropylamine‐Derived Distonic Iminium Radicals: Photoinduced Strategies in Chemo‐ and Stereo‐Selective Synthesis

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of
