Corey-Chaykovsky epoxidation is one of the versatile methods for synthesis of structurally diverse oxiranes. The extension of simplified Corey-Chaykovsky epoxidation has been investigated. Ketones and aromatic aldehydes were epoxidized in satisfactory to excellent yields with trimethylsulfonium iodide as an ylide precursor and crushed potassium hydroxide as a base in tertiary butanol. The scope and limitation of the simplified procedure were examined. The results revealed that the procedure is applicable to the epoxidation of ketones and aromatic aldehydes.
