Substoichiometric quantities (2.5–20 mol%) of Al(SbF6)3 catalyze the di(isopropyl)ethylamine-mediated cyclocondensation of various acyl halides and enolizable aldehydes to afford β-lactones in good yields (58–93%). These reactions are discussed

β-Lactone electrophiles are subject to regioselective addition–elimination (AE) or SN2 ring opening with various nitrogen-based nucleophiles. Primary and secondary amines promote AE ring opening to deliver products that are the functional equivale
