US 2026/0184675 A1 · CHIRAL ISOMERIC SULFITE COMPOUND AND APPLICATION THEREOF

Abstract

Chiral isomeric sulfite compounds, and preparative separation and application of chiral structures thereof are disclosed, which belong to the technical field of agriculture. The present disclosure has found that the chiral isomeric sulfite compounds having the structure of general formula (A) have excellent inhibitory activities against pest eggs, especially have strong inhibitory activities against eggs of thrips, mites, Lepidoptera moths, Aleyrodidae and Harmonia axyridis, and meanwhile have germicidal activity, and their absolute configuration are obtained through preparative separation. The compounds with such structures can be used for killing pest eggs and germs, and have high research value of agrochemical, having broad application prospects in the field of agricultural pharmacy.

Dependent claims

A sulfite compound having a structure as shown in formula (A) or a mesomer, a racemate, a stereoisomer and a pharmaceutically acceptable salt thereof:

wherein, R1 and R2 are independently selected from hydrogen, halogen, a substituted or unsubstituted C1-C10 alkyl, a substituted or unsubstituted C1-C10 alkoxy, a C2-C10 alkoxycarbonyl, a C2-C10 alkylcarbonyl and a C1-C10 carbonyl;
R3, R3′, R4, and R4′ are each independently selected from hydrogen, C1-C5 alkyl, C1-C5 alkenyl;
or, R3, R3′, R4, and R4′ together with the carbon atom to which they are attached form a five-membered heterocycloalkyl;
R5 is selected from halogen, and a substituted or unsubstituted C1-C10 alkyl.
