The Synthesis of O-Ethyl-O- (Substituted y-Butyrolactonylenyl-methyl) N-Alkyl (or N,N-Dialkyl) Phosphoramidothioatcs

Abstract

Abstract: In this paper, a series of new compounds were prepared by the reaction of O-ethyl-N-alkyl (or N,N-Dialkyl amidothiophosphoryl chloride with several sodium salts of a-hydroxymcthylene lac-tones in the presence of DMAP. The structure of these new compounds were confirmed by elemental analysis, ¹H NMR, ¹³C NMR, and so on. The isomerization of them had been studied. Most of the compounds have fungicidal activities at 500 ppm. They have plant growth regulation activites.

Key words: Phosphoramidothioates, Fungicidal activity, Plant growth regulation
