Catalytic asymmetric 1, 3-dipolar cycloaddition reaction of nitrones with α′-phosphoric enones by a chiral ligand-copper(II) triflate complex

Using the C2-symmetric bis-oxazoline copper(II) catalyst 6f as a chiral Lewis acid, α′-phosphoric enones 2 undergo 1,3-dipolar cycloaddition with nitrones 3 to provide isoxazolidines 4 with very high enantioselectivity and endo/exo selectivity.
