Chemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

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 ...

Sulfur‐Directed Construction of Vinyl Cyclopropanes from 1,3‐Dienes
Angewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.Sulfur takes control. A pending thioether acts as a molecular compass, directing carbene addition to the 1,3‐diene scaffold with exceptional regio‑ and diastereocontrol to forge sulfur‐substituted vinyl cyclopropanes (S‐VCPs) — molecular architectures inaccessible via conventional cyclopropanation strategies.

Total Synthesis of Roseophilin [PDF]
, 2016 The first total synthesis of the antitumor agent roseophilin 1 is reported. Its intricate macrotricyclic core 2 is obtained by means of a new palladium-catalyzed manifold for the formation of ansa-bridged pyrroles which proceeds via vinyl oxirane 8 and ...
