DETAILS

Description (English)
Packaging
1, 5 g in glass bottle
Application
A water-tolerant Lewis acid catalyst recently used in one-pot syntheses of β-lactams,2 and in stereocontrolled radical3 and nucleophilic1 addition reactions. Catalyzes the synthesis of deoxypenostatin A in a novel, stereoselective, intramolecular Diels-Alder reaction.4Lewis acid catalyst used with a silylated chinchona alkaloid in an asymmetric synthesis of substituted β-lactams from an acid chloride and aryl imine.5 Also used to catalyze an aldehyde-ene reaction in a synthesis of the guaiane skeleton.6An important Lewis acid catalyst for a variety of synthetic reactions, including allylborations.7,8
