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

ChemistryEurope, 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.

Spirocyclic Diamine Scaffolds for Medicinal Chemistry

Helvetica Chimica Acta, Volume 109, Issue 1, January 2026.
Here we enumerated 391 spirocyclic diamine drug scaffolds with ring sizes four to eight and found that most of them are unknown. We prepared four novel such spirocycles and discovered a micromolar inhibitor of the M4 muscarinic receptor. ABSTRACT Medicinal chemistry requires the exploration of structurally diverse compound families to expand the ...

Exploring Isophorone‐Based Dienones: Comprehensive Insights Into Their Synthesis, Reactivity, and Diverse Applications

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Isophorone is an important motif in synthetic organic chemistry, as it is highly reactive and can get involved in a diverse array of functional group transformations to access various synthetic intermediates and molecular targets. In this context, an important group of compounds is the conjugated or nonconjugated isophorone‐cored dienones, which are ...

Highly efficient construction of angular polycycles

Nature Communications
Angular tricyclic and polycyclic skeletons feature typical cores in an intriguing type of natural products. We herein report the Lewis acids-catalyzed dearomative (3 + 2) cycloadditions of donor-acceptor cyclopropanes with benzene ring, by which ...
