A one-pot, three-component synthesis of benzimidazole-linked thiazolidines from 2-cyanomethyl benzimidazole, iso-, isothio-, or isoselenocyanates and 1,2-dichloroethane is reported. Isolation of the key intermediate formed during the course of the reaction validates its mechanistic pathway. Under the same reaction conditions, benzimidazole-linked/fused thiazinanes were obtained when 1,3-dichloropropane or diiodomethane was used.

一锅合成不对称的双杂环：苯并咪唑，苯并恶唑和苯并噻唑连接的噻唑烷。

据报道，由2-氰基甲基苯并咪唑，异-，异硫代或异异戊烯酸酯和1，2-二氯乙烷一锅三组分合成苯并咪唑连接的噻唑烷。反应过程中形成的关键中间体的分离验证了其机理途径。在相同的反应条件下，当使用1,3-二氯丙烷或二碘甲烷时，可获得苯并咪唑连接/稠合的噻嗪酮。
