Synthesis of new organothiophosphorus insectoacaricides containingN-acylated amino acid fragments

Methods for the synthesis ofO-alkylS-(N-acyl-N-alkoxycarbonylalkyl)aminomethyl (methyl)thio- and -dithiophosphonates based on the reaction between alkaline-metal salts ofO-alkyl (methyl)thio- and -dithiophosphonates and N-alkoxycarbonyl-N-chloromethylglycine or --alanine esters and by treatment ofO-alkyl (methyl)dithiophosphonoates andN-acylated amino acids or their esters with paraform in the presence of HCl were developed. The compounds obtained exhibit high insectoacaricide activity and selectivity.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 7, pp. 1294–1301, July, 1994.
