title: N-heterocyclic carbene-catalyzed [4 + 1] annulation of phthalaldehyde and imines.
abstract: The diastereoselective synthesis of cis-2-amino-3-hydroxyindanones was realized by the N-heterocyclic carbene-catalyzed [4 + 1] annulation of phthalaldehyde and imines, which may involve a tandem aza-benzoin reaction and aldol reaction.
