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.

Photocatalytic Synthesis and Palladium‐Catalyzed Functionalizations of Hydrofluoroolefin (HFO‐1234ze)‐Based Vinyl Iodides

Advanced Synthesis &Catalysis, Volume 368, Issue 18, 19 September 2026.
An inexpensive industrial refrigerant, HFO‐1234ze, is transformed into a versatile fluoroalkyl building block via a scalable, solvent‐free protocol. Utilizing the metal‐free photocatalyst 4CzIPN, efficient visible‐light‐induced radical addition to alkynes reveals distinct, substrate‐dependent stereoselectivities.

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 ...

Unified Synthesis of Unconventional α‐Polyhalogenated Amines Through Hydroaminoalkylation

Angewandte Chemie International Edition, Volume 65, Issue 38, 14 September 2026.
A unified, redox‐neutral method that transforms alkenes and alkynes into α‐polyhalomethyl amines using stable hemiaminal reagents is reported. This approach enables access to CF3, CF2H, CF2Cl, and CFClH motifs, expanding halogenated amine space with broad substrate scope, functional group tolerance, and applicability to late‐stage modification of drug ...

A Bio‐Based Chiroptical Overcrowded Alkene From Flavanone: Photoreactivity and Theoretical Investigation

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
A sustainable route to photoresponsive molecular systems is achieved using the bio‐based flavanone (‐)‐isolonchocarpin from Tephrosia vogelii. Through McMurry homocoupling and light‐driven 6‐π‐electrocyclization, an overcrowded alkene and a fluorescent O‐heterocyclic phenanthrene are synthesized.
