DMAPO/Boc2O‐Mediated One‐Pot Direct N‐Acylation of Sulfoximines with Carboxylic Acids
European Journal of Organic Chemistry, EarlyView.The one‐pot direct N‐acylation of NH sulsoximines with carboxylic acids is described. The method can be performed under mild low‐temperature reaction conditions and exhibits a wide substrate scope (> 60 examples). The present method is operationally simple, scalable, and practical; thus, it can find wide applications in both academic and industrial ...

Cross‐Coupling Reactions in Aqueous Micellar Media
European Journal of Organic Chemistry, EarlyView.Aqueous micellar media have emerged as sustainable alternatives to organic solvents for small‐molecule synthesis. This Review discusses the evolution of surfactants for synthesis, their application to cross‐coupling reactions, the benefits for reactivity and sustainability, and the remaining challenges in this rapidly growing field.

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research
Mass Spectrometry Reviews, EarlyView.ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...
