A chemoselective tandem Knoevenagel-nucleophilic epoxidation reaction using acetonitrile derivatives and aldehyde as starting materials, water as the solvent, and tert-butyl hydroperoxide (TBHP)-1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as the catalytic system to synthesize a series of cyanoepoxides with good yields is developed. This synthetic strategy is environmentally friendly, simple to operate, conducted under mild reaction conditions, and utilizes readily available starting materials with a broad substrate scope. It offers an efficient and green approach for the synthesis of structurally diverse cyanoepoxides.

Key words: cyanoepoxide, nucleophilic epoxidation, chemoselectivity, aqueous solvent
