Synthesis and Biological Activities of Methyl 1-(5-Methyl Isoxazol-3-oxy Acetoxy) Alkyl Methyl Phosphinates

Methyl 1-(5-methyl isoxazol-3-oxy acetoxy) alkyl methyl phosphinates were synthesized by the condensation of O-methyl methyl 1-hydroxyalkyl phosphinates moiety with 5-methyl isoxazol-3-oxy acetyl chloride and were tested for plant growth regulatory activity and herbicidal activity. Some compounds exhibited notable plant regulatory activity and herbicidal activity.
