Regioselective C‐H Oxyfunctionalization of Aliphatic Acids Through a Consecutive Biosolar Cascade

Small, EarlyView.
Photobiocatalytic regioselective oxyfunctionalization of aliphatic acids is realized by combining a dual‐alkali‐metal‐doped carbon nitride photocatalyst (NaK‐ACN) with CYP152A1 peroxygenase. The synergistic effect of co‐dopants modulates electron distribution and the surface electric field, enhancing 2e− ORR activity.

The investigation of optimum condition of natural rubber epoxidation reaction in latex phase

Majalah Kulit, Karet, dan Plastik, 2021
Natural rubber (NR) latex epoxidation is a chemical modifcation of natural rubber to produce natural rubber with higher polarity (oil resistant) which is commonly called epoxidized natural rubber (ENR). ENR is produced from the reaction of natural rubber

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.

Opportunities and Challenges in Electrolytic Propylene Epoxidation

, 2022
Propylene oxide (PO) is an important chemical. So far, its synthesis protocol relies on expensive oxidants. In contrast, direct epoxidation of propylene (DEP) using molecular oxygen is considered ideal for PO synthesis.

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

Insect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.
