European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.The intramolecular nitrile oxide olefin [3 + 2]‐cycloaddition offers a reliable entry toward 2‐aza‐bicyclo[4.3.0]‐nonanes, a substructure found in several bioactive piperidine alkaloids. The required oxime precursors were prepared in non‐racemic form by Ir‐catalyzed asymmetric allylation and ring‐closing metathesis.

Structurally Constrained Stibenium: Metallomimetic C−Si Bond Activation
Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.A structurally constrained stibenium cation supported by a 2,6‐bis(o‐carborano)pyridine pincer‐type ligand was prepared, and its preliminary reactivity toward silanes was investigated. Remarkably, Si−C bonds in silanes undergo activation via an oxidative‐addition‐type process at the cationic Sb center.

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.Chiral tri‐ and pentahydroxy spirocyclopentane‐indolizidines were synthesized using lithium diisopropylamide “LDA” promoted diallylation and tetrahydrofuran “THF” ring‐opening in a one‐pot procedure as a key step. The sequence leading to the targeted hydroxy‐spiroindolizidines was achieved by cis‐dihydroxylation followed by reduction of the enamine and

A Short Total Synthesis of the Daucane Sesquiterpenoid Ferutinin
European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.Only nine steps were required to access the bioactive daucane sesquiterpene ester ferutinin (1) from 3‐methyl‐2‐cyclopentenone (3) and allyl p‐tolyl sulfoxide. A one‐pot 1,4‐addition/aldol sequence was used to rapidly provide diene 2 (TBS = tert‐butyldimethylsilyl), ring‐closing metathesis of which followed by alkylation and acylation gave rise to the ...

1,1‐and 1,2‐Diborylalkenes: Preparation and Synthetic Applications
Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.In this review, we highlight recent advances in the synthesis and reactivity of 1,1‐diborylalkenes and 1,2‐diborylalkenes, along with various transformations leading to C‐C, C‐heteroatom, and multicomponent products. By providing a comprehensive and practical resource, this review aims to assist researchers in exploring the synthetic utility of 1,1 and
