Efficient Enantiomeric Selectivity Separation Via Homochiral Graphene Oxide Membrane

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A new type of chiral graphene oxide (GO) membrane is proposed that exhibits a separation factor of up to 20.1 as well as a preferential enantiomer flux of 4.5 mmol m−2 h−1. Moreover, the only first FPLC‐compatible column has been further developed via stacking these chiral GO membranes.

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 ...

Formal Synthesis of the Akuammiline Alkaloid (±)‐Strictamine via a (4 + 2) Annulation Reaction With a Donor–Acceptor Cyclobutane

Helvetica Chimica Acta, EarlyView.
We report a concise formal synthesis of (±)‐strictamine via a silylium‐catalyzed (4 + 2) annulation of a donor–acceptor cyclobutane, achieved in 13 steps from tryptamine. ABSTRACT The akuammiline alkaloids are complex monoterpene indole natural products with a rigid cage‐like architecture and diverse biological activities.
