Various epoxides are readily converted to their corresponding thiiranes by thiourea/zeolite molecular sieve 4 system in refluxing MeOH. All reactions were carried out within 12-25 min to give thiiranes in 80%-99% yields. The catalyst saves its catalytic activity for several times at this transformation. Stereospecific conversion of (R)-(+)-styrene oxide to (S)-(+)-styrene episulfide was achieved by this combination system. Taylor & Francis Group, LLC.
