Title: Synthesis and Biological Activity of Some Novel <i>O</i>-Phosphorylated Benzoxazole Derivatives
Abstract: The phosphorylation of 2-(2′-hydroxyphenyl) benzoxazole has been accomplished with phosphorus oxychloride in a 1:1, 2:1, and 3:1 molar ratio in the presence of a base to yield O-phosphorylated benzoxazole derivatives. Their structures were confirmed by elemental analyses and IR, 1H NMR, and 31P NMR spectral studies. These compounds have been screened for their insecticidal activity against Periplenata americana and were found to be quite active in this respect.
