Synthesis of Oxazolyl‐Piperidines Bearing a Quaternary Stereocenter Through a Multicomponent Reaction Involving α‐Isocyanoacetates and Piperidones

European Journal of Organic Chemistry, EarlyView.
Straightforward access to oxazole‐containing piperidines through a multicomponent reaction from α‐isocyanoacetates is described. By expanding the reactivity of these a‐isocyanoacetates from aldehydes to ketones, this process efficiently delivers oxazolyl‐piperidines bearing a quaternary stereocenter as valuable scaffolds relevant to drug discovery.

Mesityl‐Substituted Azuleno[1′,2′:4,5]pyrrolo[2,3‐b]quinoxalines: Synthesis, Functionalization, Photophysical, and Electrochemical Properties

European Journal of Organic Chemistry, EarlyView.
Azuleno[1′,2′:4,5]pyrrolo[2,3‐b]quinoxaline with a mesityl group as a solubilizing group was synthesized. By synthesizing derivatives in which various functional groups were introduced into two electronically distinct sites, the pyrrole nitrogen atom and the azulene five‐membered ring, we were able to reveal that the photophysical and electrochemical ...

Synthesis of Benzopyran Atropisomers via Electrophilic Halogenation

European Journal of Organic Chemistry, EarlyView.
We report a halogenation‐based method for the synthesis of axially chiral benzopyrans, tolerating diverse substituents and halogens (Br, Cl, and I). A double bromination gives bisbenzopyrans with two stereogenic axes. Preliminary enantioselective conditions yield benzopyran atropisomer with up to 56% ee.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
