Synthesis and herbicidal activity of isoxazole-substituted 1-aminoethylphosphonates and 1-hydroxyethylphosphonates

Isoxazole‐substituted 1‐aminoethyl‐ and 1‐hydroxyethyiphosphonates were synthesized by a multi‐step procedure and were screened for herbicidal activity against Lepidium sativum L. and Cucumis sativus L. All the synthesized compounds exhibited notable herbicidal activity.
