Herein,
by dual C–O bond cleavage of cyclic ethers with
Cu catalysis, we eventually led to the development of a selective
three-component coupling of commercially available chemicals, carboxylic
acids, ethers, and halogens to synthesize more than 70 iodoalkyl esters
in the presence of TMSCF<sub>3</sub>. This allows for the concise
synthesis of highly functionalized iodoalkyl esters directly. And
the synthetic insect pheromones were also disclosed.
