Asymmetric Synthesis of Tertiary α‐Aryl Stereocentres in Tetrahydro‐4H‐pyran‐4‐ones Using Pd‐Catalyzed Decarboxylative Asymmetric Protonation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The Pd‐catalyzed decarboxylative asymmetric protonation (DAP) has been developed for sterically hindered tetrahydro‐4H‐pyran‐4‐one derived α‐aryl‐β‐keto esters. A substrate scope of nine examples of DAP showed that substrates containing a di‐ortho methoxy substitution pattern on the aryl ring gave rise to the highest enantioselectivities of up to 85 ...

Synthesis of β‐ and γ‐Carbolinones Through a Fe(III)‐Mediated Radical 6‐Endo‐Trig Cyclization of Indole‐Based Ugi 4‐CR Adducts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A practical strategy for synthesizing β‐ and γ‐carbolinones from indole‐based Ugi 4‐CR adducts through an intramolecular radical cyclization using Fe(III)–H species is presented. This approach enables the efficient synthesis of spiro‐carbolinones under mild reaction conditions and demonstrates the effectiveness of secondary radicals in both cyclization

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.
