Ae. Shipov et al., SYNTHESIS OF NEW ORGANOTHIOPHOSPHORUS INSECTOACARICIDES CONTAINING N-ACYLATED AMINO-ACID FRAGMENTS, Russian chemical bulletin, 43(7), 1994, pp. 1231-1238
Methods for the synthesis of O-alkyl cyl-N-alkoxycarbonylalkyl)aminome
thyl(methyl)thio- and -dithiophosphonates based on the reaction betwee
n alkaline-metal salts of O-alkyl (methyl)thio- and -dithiophosphonate
s and N-alkoxycarbonyl-N-chloromethylglycine or -beta-alanine esters a
nd by treatment of O-alkyl (methyl)dithiophosphonoates and N-acylated
amino acids or their esters with paraform in the presence of HCl were
developed. The compounds obtained exhibit high insectoacaricide activi
ty and selectivity.
