METAL-HYDRIDE REDUCTION OF ISOXAZOLINE-3-CARBOXYLATE ESTERS
, 1986 The reduction of a series of isoxazolino-3-carboxylate esters with sodium borohydride gave 3-(hydroxymethyl)isoxazolines in 34-98% yield. Reduction with DIBAH gave isoxazoline-3-carboxaldehydes in 63 and 85% yields for the two reactions studied ...

Application of chiral 2-isoxazoline for the synthesis of syn-1,3-diol analogs
Beilstein Journal of Organic Chemistry, 2019 The asymmetric cycloaddition of TIPS nitronate catalyzed by “Cu(II)-bisoxazoline” gave the 2-isoxazoline product in 95% yield, which was converted into tert-butyl (3S,5R)-6-hydroxy-3,5-O-isopropylidene-3,5-dihydroxyhexanoate in 14 steps through a β ...

Pest Management Science, EarlyView.The inheritance of methomyl resistance in Dalbulus maidis is autosomal, incompletely dominant and polygenic. No cross‐resistance was found between methomyl and chlorfenapyr, cyantraniliprole and isocycloseram. Abstract BACKGROUND Acetylcholinesterase (AChE) inhibitor insecticides have been important tools for the management of Dalbulus maidis in Brazil;

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.

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.
