The structure of osthole has been modified to improve its larvicidalactivity against mosquitoes. A new efficient synthesis of ostholederivatives with Grignardreagents has been developed, which employs CuI and LiCl as promoters and covers a broad range of substrates to afford the corresponding products in mild to good yields (up to 83%). Bio‐activity evaluation showed that several products exhibited
