Current Status of Organophosphorus Insecticide and Stereochemistry

Abstract

Current status of chiral organophosphorus agrochemicals is firstly reviewed in terms of steric structure-activity relationships in insect, disease and weed control. Recent progress in the synthesis and reaction of chiral organophosphorus compounds is then described: asymmetric synthesis of organophosphorus synthetic intermediates with asymmetric induction at phosphorus center in the molecule, configuration and conformation of cyano-salithion and its derivatives, and stereochemical course in the conversion of α -aminoalkylphosphonic acids into α -hydroxyalkylphosphonic acids with nitrous acid.
