Modular, Tricomponent, and Concurrent One‐Pot Synthesis of Libraries of γ‐Keto Sulfones and γ‐Keto Phosphine Oxides using Brønsted Acidic Eutectic Mixtures

open access: yesChemSusChem, EarlyView.
This study presents a sustainable, metal‐free, one‐pot synthesis of γ‐keto sulfones and phosphine oxides using a ChCl/p‐TSA·H2O eutectic mixture. The method enables regioselective CC and CX bond formation under mild conditions, aligning with Green Chemistry Principles.

Testing Differently Substituted Quinoxaline‐2,3‐Dithiolate Ligands in Z‐Stereoretentive Olefin Metathesis Leading to Pheromone of Rice Yellow Stem Borer (Scirpophaga incertulas)

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
A set of Z‐stereoretentive olefin metathesis catalysts was tested in the synthesis of a pheromone of rice yellow stem borer (Scirpophaga incertulas)—one of the major rice pests in Asia. ABSTRACT Stereoselective olefin metathesis offers access to geometrically well‐defined C–C double bonds and is considered a promising new method for transforming plant ...

Which diuretics are safe and effective for patients with a sulfa allergy? [PDF]

open access: yes, 2007
Diuretics that do not contain a sulfonamide group (eg, amiloride hydrochloride, eplerenone, ethacrynic acid, spironolactone, and triamterene) are safe for patients with an allergy to sulfa.

A Critical Overview of Common Foodborne Toxicants and Methods for Their Reliable Detection

open access: yesFood Frontiers, EarlyView.
ABSTRACT Food is an essential commodity for human health. However, toxicants such as mycotoxins, heavy metals, acrylamide, and pesticides can be present in food either naturally or through processing, packaging, or some anthropogenic activities. A thorough review of carefully selected studies revealed that climate change and pandemics have led to an ...
