Asymmetric sulfite isomers and preparations containing these compounds.

Abstract

The invention relates to chiral isomer sulfite compounds, the separation, preparation and application of these chiral structures, in the field of agricultural engineering. The invention shows that chiral isomer sulfite compounds with a general formula (A) structure exhibit superior inhibitory activity against pest eggs, particularly strong inhibitory activity against the eggs of thrips, tree mites, caterpillars (Lepidoptera), Aleyrodidae family and ladybug Harmonia axyridis, and also exhibit antimicrobial activity, and their absolute structure is determined through separation and preparation. Compounds with this structure can be used to kill pest eggs and microorganisms, have high research value in the field of agricultural chemistry and have broad application potential in the agricultural pharmaceutical industry.
