A direct and efficient approach to 1,3,5-trisubstituted benzenes has been developed via N-heterocycliccarbene-catalyzed [2 + 4] annulation of α-bromoenals and α-cyano-β-methylenones. The reaction worked well for both aryl- and alkylenones.

A DBU-mediated synthesis of 1,3,5-trisubstituted benzenes was developed via the [2 + 4] annulation of in situ activated α,β-unsaturatedcarboxylic acids and α-cyano-β-methylenones. The dual role of DBU as Brønsted base and nucleophilic Lewis base is the key for the success of the reaction.
