Ring Formation in Sesquiterpene Synthesis: Biomimetic vs. Non‐Biomimetic Strategies

European Journal of Organic Chemistry, EarlyView.
A short review of cyclase enzyme‐mediated ring formation in sesquiterpene biosynthesis is presented as a prelude to six case studies examining the merits and demerits of biomimetic vs. non‐biomimetic strategies for carbocyclisation in the total synthesis of this iconic natural product class.

Synthesis of Sulfur Enriched Cyclohexenes via the Tungsten‐Promoted Dearomatization of a Phenyl Sulfone

European Journal of Organic Chemistry, EarlyView.
A method for synthesizing sulfur‐substituted cyclohexenes is reportedthat leverages the η2‐coordination of a phenyl sulfone to [WTp(NO)(PMe3)] (Tp = trispyrazolylborate). Three sequential protonation and nucleophilic additions to the bound arene, followed by oxidative decomplexation, affords functionalized cyclohexenes bearing sp3‐ and sulfur‐enriched ...

Enantioselective Determination of Amphetamine‐Type Stimulants in Environmental Waters Using SPE and CE–MS/MS

ELECTROPHORESIS, EarlyView.
ABSTRACT The growing concern over drug abuse, particularly involving amphetamine‐type substances (ATS), has led to their monitoring in environmental waters. These chiral compounds, commonly found in river water and wastewater treatment plant (WWTP) effluents, require analytical methods capable of enantiomeric discrimination, as their enantiomers can ...
