Intermolecular Stetter reaction of aromatic aldehydes with(E)-(2-nitrovinyl)cyclohexane catalyzed by thiazolium A has been developed.The reaction rate and efficiency are profoundly impacted by the presence of thiourea B.The reaction affords moderate to good yields of the Stetter product.Some factors influencing yield were discussed.
