Synthesis and Larvicidal Activity of Phrymarolin Derivatives against Culex pipiens pallens.


Twenty-eight new phrymarolin derivatives, including twenty-one ethers, six esters and a dehydroxy phrymarolin, were prepared from phrymarolin I and the structures of all the derivatives were confirmed by ¹H NMR and ¹³C NMR spectroscopic and MS data analyses. Larvicidal activities of these phrymarolin analogues were assayed against 4th instar larvae of Culex… (More)
