Sulfur‐Directed Construction of Vinyl Cyclopropanes from 1,3‐Dienes

Angewandte Chemie, EarlyView.
Sulfur takes control. A pending thioether acts as a molecular compass, directing carbene addition to the 1,3‐diene scaffold with exceptional regio‑ and diastereocontrol to forge sulfur‐substituted vinyl cyclopropanes (S‐VCPs) — molecular architectures inaccessible via conventional cyclopropanation strategies.

Spatial Detection of Microsphere Polystyrene Plastics and Molecular Remodeling within a Full‐Body Mouse with MALDI Trapped Ion Mobility Mass Spectrometry Imaging

Angewandte Chemie, EarlyView.
Orally administered polystyrene microplastics accumulate in murine tissues and are detected using MALDI‐MSI with TIMS. Lipid profiling reveals decreases in hexosylceramides, sphingomyelins, and ether‐linked phospholipids, indicating altered metabolism.

Strategies Toward Accessing Enantioenriched (Hetero)Benzo‐Fused 5‐ and 6‐ Membered Rings via Intermolecular Carbometalation

Angewandte Chemie, EarlyView.
The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.
