A mild, sustainable and efficient organocatalytic synthesis of thiiranes from alkenes has been developed. Starting from olefins and utilizing the epoxidation protocol developed in the Kokotos’ group, which employs 2,2,2-trifluoroacetophenone as the organocatalyst and H₂O₂ as the oxidant, followed by ring opening by thiourea, a variety of thiiranes were synthesized in moderate to excellent yields.
