Synthesis of Microbial‐Derived Octadecanoids

Lipids, EarlyView.
C18‐carbon containing dietary polyunsaturated fatty acids (e.g., linoleic acid, α‐linolenic acid, and γ‐linolenic acid) are metabolized by bacteria in the gut into oxygenated lipid mediators termed octadecanoids. To study the biological function of these compounds, we report here the chemical synthesis of multiple octadecanoids.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Chiral Bifacial Indacenodithiophene‐Based Hole‐Transport Materials With Chirality‐Induced Spin Selectivity: Chirality‐Spin Polarity Correspondence and Perovskite Passivation

Small, EarlyView.
Homochiral bifacial indacenodithiophene (IDT)‐based hole‐transport materials form amorphous spin‐coated films showing pronounced chirality‐induced spin selectivity (CISS) with spin polarization ≈ 60%, and reveal a robust chirality–spin‐polarity correspondence.

Development of an Efficient Stereoretentive Para‐Claisen‐Cope Rearrangement

ChemistryEurope
A stereoretentive para‐Claisen‐Cope rearrangement of chiral aryl‐allyl ethers is reported, achieving near‐perfect chirality transfer thereby furnishing products with exceptional enantiomeric excess (up to > 98% ee) as single regioisomers.

Crystallization‐Driven Helical Conjugated Polymer Nanowires for Circularly Polarized Light‐Addressable Ferroelectric Physical Unclonable Functions

Small, EarlyView.
Supramolecular helicity meets ferroelectricity: P3HT‐b‐PMMA helical nanowires enable handedness‐specific modulation of remanent polarization in P(VDF‐TrFE) hybrids. This platform demonstrates the first CPL‐addressable ferroelectric PUF, translating molecular chirality into secure digital authentication.

DFT‐assisted rational design of salan ligands for highly enantioselective Zr–salan‐catalyzed hydroxylation of cyclic β‐keto esters

Smart Molecules, EarlyView.
Guided by DFT calculations, the design of novel C1‐symmetric salan ligands without the involvement of Suzuki coupling was achieved, and the preparation of α‐hydroxy‐β‐ketoesters in 99% yield and 99% ee was realized under low catalyst loading. Abstract In this work, a structurally simple, inexpensive, and readily accessible Zr–salan catalytic system was

Modular Synthesis of α‐Quaternary Pyrrolines by Pyridoxal‐Catalyzed Sequential Reactions With Precise Chirality Relay

Transformative Chemistry, EarlyView.
Direct asymmetric α‐C conjugate addition of aminoacetonitrile enabled by carbonyl/iminium double activation, together with subsequent electrophilic functionalization, offers a one‐pot, two‐step modular strategy for synthesizing chiral α‐quaternary pyrrolines with precise chirality relay and high structural diversity.

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.

Temperature interacts with jack pine host defences to influence the growth of mountain pine beetle‐associated fungi

Agricultural and Forest Entomology, EarlyView.
Optimal growing temperatures varied with mountain pine beetle‐associated fungal species. There was only a marginal impact of temperature on the response of fungi to defensive monoterpenes of novel host pine. Interspecific facilitation occurred for Leptiographuim longiclavatum when grown in Ophiostoma montium‐induced treatments at optimal temperatures ...
