Trimethylsilyl cyclopropyl ethers can react with the silica gel to form the cyclopropanols when Lewis acid such as ZnX~2 existed. Then the esterification reaction between trimethylsilyl cyclopropyl ethers and acid chloride in the presence of ZnCl~2 were investigated, and better yields were obtained in less electron-donating solvent CH~2Cl~2 than in Et~2O. Moreover, we adopted an one-pot route combining the cyclopropanation and esterification of enoxysilane to prepare the cyclopropyl esters in moderate to good yields.
