Application: A water-tolerant Lewis acid catalyst recently used in one-pot syntheses of β-lactams, and in stereocontrolled radical and nucleophilic addition reactions. Catalyzes the synthesis of deoxypenostatin A in a novel, stereoselective, intramolecular Diels-Alder reaction.
Lewis acid catalyst used with a silylated chinchona alkaloid in an asymmetric synthesis of substituted β-lactams from an acid chloride and aryl imine. Also used to catalyze an aldehyde-ene reaction in a synthesis of the guaiane skeleton.
An important Lewis acid catalyst for a variety of synthetic reactions, including allylborations.7,
