Regioselective Oxidative Oligomerization of 2‐Tert‐Butylpyrene Toward Structurally Defined Oligomers and Their Application in Organic Light‐Emitting Diodes

European Journal of Organic Chemistry, Volume 29, Issue 36, 24 September 2026.
Treatment of 2‐tert‐butylpyrene with Cu2+ afforded structurally well‐defined pyrene oligomers, up to the 13‐mer. Single‐crystal X‐ray diffraction, spectroscopic analyses, and computational studies were conducted to evaluate the properties of the resulting oligopyrenes.

A Straightforward Synthesis of Benzestrol by Matteson Homologation Using Chiral Benzyl Carbamates

European Journal of Organic Chemistry, Volume 29, Issue 36, 24 September 2026.
Benzestrol can easily be obtained stereoselectively via Matteson reaction using chiral Boronic esters and chiral benzyl carbamates. A straightforward and highly stereoselective synthesis of the non‐steroidal estrogen benzestrol is described based on Matteson homologations.

Toward the Synthesis of Pestalustaine A: Structural Revision and Formation of Original Strained Tricyclic Architectures

Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Our synthetic endeavor toward the total synthesis of the reported unprecedented tricyclic skeleton of the sesquiterpene pestalustaine A allowed us to perform divergent cyclizations of a bicyclo[4.4.1]undec‐3‐ene into complex tricyclic architectures and to revise the structure of the natural product.

Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis

ChemSusChem, Volume 19, Issue 17, 14 September 2026.
This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.

Borylcyclopropanes: Synthetic Strategies and Applications

Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

Covalent Insertion of a Mn(Salen) Type Complex in Cross‐Linked Protein Crystals: Design of an Enantioselective Artificial Epoxidase

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
An Artificial metalloenzyme was designed by a Michael addition between a MnSalen complex and a cysteine residue within NikA crystals. The heterogeneous catalyst was found capable of an enantioselective and stereospecific epoxidation of cis‐β‐methylstyrene in cristallo.
