Water makes the difference: an example of the Lewis acid-surfactant-combined catalyzed synthesis of biologically significant 4-aminocyclopentenones was developed.

Lewis acid-surfactant-combined catalyzed synthesis of 4-aminocyclopentenones from glycals in water

4-Aminocyclopentenones were synthesized from readily available glycals and secondary anilines, with the aid of a Lewis acid–surfactant-combined catalyst. The reactions proceededvia a 4π conrotatory electrocyclization, affording the corresponding 4-aminocyclopentenones in good yields with excellent diastereoselectivities.
