Indole Synthesis via Allenyl Ester; Enantioselective Total Synthesis of Geissoschizoline

ChemistryEurope, EarlyView.
An indole synthesis via an allenyl ester intermediate at ambient temperature has been developed. The mild reaction conditions allow the use of a broad range of substrates. Notably, the utility of this approach is demonstrated through the asymmetric total synthesis of geissoschizoline, a Strychnos‐type monoterpenoid indole alkaloid.

Advances in Enaminomaleimides Chemistry: Synthesis, Chemical Applications, and Perspectives

ChemistryEurope, EarlyView.
Enaminomaleimides are versatile building blocks for the construction of functionalized heterocycles. Their unique nucleophilic character, contrasting with the classical electrophilic nature of maleimides, enables diverse synthetic applications, showing promising potential in both materials science and medicinal chemistry.

Analysis of triacylglycerol and phospholipid sn‐positional isomers by liquid chromatographic and mass spectrometric methodologies

Mass Spectrometry Reviews, EarlyView., 2023
Abstract Analysis of triacylglycerol (TG) and phospholipid sn‐positional isomers can be divided into two main categories: (a) direct separation by chromatography or other means such as ion mobility mass spectrometry and (b) quantification of regioisomer ratios by structurally informative fragment ions with mass spectrometric methods.
