Synthesis of Aminocyclopropanes by Redox‐Neutral Aminoalkylation

Angewandte Chemie International Edition, EarlyView.
Aminocyclopropane synthesis by hydroaminoalkylation utilizing cheap, readily available starting materials is presented, offering orthogonality to commonly used methods and allowing broad functional‐group tolerance. Solvent‐mediated conditions enable the reaction of a pre‐formed hemiaminal with alkenes and alkynes.

Nickel‐Catalyzed Reductive Cross‐Coupling of Xanthate Esters With Aryl and Alkenyl Iodides

Chemistry – A European Journal, EarlyView.
A nickel‐catalyzed reductive cross‐coupling of xanthate esters and aryl/alkenyl iodides is reported without the need for separate activators for the xanthate esters. The reaction utilizes a relatively low catalyst loading. Diarylmethanes with a good functional group variety can thus be synthesized indirectly from the corresponding benzylic alcohols ...

Asymmetric Copper-Catalyzed [2,3]-Sigmatropic Rearrangements of Alkyl- and Aryl-Substituted Allyl Sulfides

, 2016
The asymmetric copper-catalyzed generation and subsequent [2,3]-sigmatropic rearrangement of sulfur ylides is strongly dependent on the structure of the starting allyl sulfide.

Enhanced Degradation of Vinyl Copolymers Based on Lipoic Acid

Journal of Polymer Science, Volume 63, Issue 6, Page 1345-1351, 15 March 2025.
ABSTRACT The introduction of degradable units into the backbone of commodity vinyl polymers represents a major opportunity to address the societal challenge of plastic waste and polymer recycling. Previously, we reported the facile copolymerization of α‐lipoic acid derivatives containing 1,2‐dithiolane rings with vinyl monomers leading to the ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...
