π‐Extended Silyl Enolates as Emerging Platforms in Radical Chemistry
European Journal of Organic Chemistry, Volume 29, Issue 36, 24 September 2026.This review covers the emerging role of π‐extended silyl polyenol ethers in radical chemistry. It highlights their versatile roles as electron‐rich SOMOphiles, silyl radical cation precursors, and nucleophilic partners in radical–polar crossover manifolds, while considering recent advances in photoredox catalysis, electrochemistry, and transition metal‐

Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.A photochemical platform enables β–β coupling of cyclopropyl silyl ethers with electron‐deficient alkenes. The resulting adducts serve as entry points into annulative and radical–polar crossover pathways, providing rapid access to fused, bridged, and spirocyclic architectures, including late‐stage scaffold diversification to diterpene‐like carbocyclic ...

Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol
Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...

Titanium‐Catalyzed Diastereoselective Keto‐ and Iminonitrile Cyclizations
Chemistry – A European Journal, Volume 32, Issue 35, 19 September 2026.The titanium(III)‐catalyzed diastereoselective cyclization of readily‐available substituted ketonitriles gives cyclopentanones in good yield and stereoselectivity. Subsequent 1,2‐addition allows the preparation of cyclopentyls with three consecutive stereocenters.

Palladium-Catalyzed [1,3]-O-to-C Rearrangement of Pyrans toward Functionalized Cyclohexanones
, 2016 Functionalized cyclohexanones are prepared from cyclic enol ethers via a Pd-catalyzed [1,3]-O-to-C rearrangement reaction. α-Arylketones are generated with excellent diastereocontrol when basic phosphine ligands are used.
