Fluorescent Diarylethenes With Polar Groups: Synthesis, Spectra, and Optical Microscopy Applications
Chemistry – A European Journal, EarlyView.Blinking green and flashing red: photo‐switchable and photo‐activatable probes emitting green and red light were prepared and applied as bioconjugates in super‐resolution optical microscopy. ABSTRACT The use of photoactivatable fluorescent diarylethenes (fDAEs) in biology‐related light microscopy has been restricted by the lack of probes having freely ...

A General Strategy for the Synthesis of Jerangolids Enabled by π‐allyl Stille Coupling
Chemistry – A European Journal, EarlyView.A general strategy for the synthesis of jerangolids is established, featuring a late‐stage π‐allyl Stille coupling of two advanced, highly customizable building blocks to form the skipped diene core. The approach provides access to all naturally occurring jerangolids, including jerangolid H, whose configuration is confirmed by NMR analysis.
