Cooperative Rh2(OAc)4/Chiral Phosphoric Acid‐Catalyzed (3 + 3)‐Cycloadditions of Pyrrole‐3‐Methides and Carbonyl Ylides

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 1, January 2026.
A stereoselective one‐step (3 + 3)‐cycloaddition between in situ generated pyrrole‐3‐methides and carbonyl ylides has been developed using cooperative rhodium and chiral phosphoric acid catalysis. The reaction affords oxa‐bridged cyclohepta[1,2‐b]pyrroles bearing three stereogenic centers, including two quaternary ones, in high yields and ...

Pivotal Synthesis of Tetrasubstituted Epoxides from Ketones and α‐Halo B/Si Ylides with Understanding of the Activation Modes

open access: yesChemistryEurope, Volume 4, Issue 1, January 2026.
The preparation of diastereoselective 1,1,2,2‐tetrasubstituted borosilylepoxides is described, involving the epoxidation of ketones with α‐monohalo borylsilylmethane reagents. The nature of the ambiphilic reagent suppressed the Boron‐Wittig olefination.

The Chemistry of Subphthalocyanines: Synthetic Strategies for their Axial, Peripheral, and Remote Postfunctionalization

open access: yesChemistryEurope, Volume 4, Issue 1, January 2026.
From axial and peripheral reactivity to remote derivatization, the chemical versatility of subphthalocyanines (SubPcs) renders them ideal scaffolds for the design of advanced functional materials. This review assembles the synthetic toolbox, key reaction conditions, and future challenges in SubPc functionalization, guiding the development of next ...
