Abstract Intermolecular Stetterreaction 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.

carbonyl anion species in situ allow for conjugateadditions in good yield to sensitive nitroalkene electrophiles. The process is tolerant of a variety of thiazolium carbinols and nitroalkene substrates and can be rendered enantioselective and diastereoselective by the addition of a chiral thiourea derivedfrom quinine.
