Abstract
TMG-catalyzed [3 + 2] organocatalytic 1,3-dipolar cycloaddition reactions of allyl ketones with in situ generated nitrile oxides have been developed. This strategy could generate 3,5-disubstituted isoxazolines in high yields and regioselectivities.

Abstract
In the title compound, C34H25NO3, the five-membered heterocyclic ring adopts an envelope conformation with the N atom as the flap. The plane through the four basal atoms of this ring makes dihedral angles of 69.78 (13), 53.15 (12) and 86.42 (13)°, respectively, with the benzene rings of the benzyl group and the two phenyl-methanone groups at the 4 and 5 positions, and of 78.60 (11)° with the naphthalenyl system. In the crystal, the mol-ecules are linked through C-H⋯O and C-H⋯π contacts into layers parallel to (101).

Abstract
A novel route to the synthesis of Delta2-isoxazoline derivatives is described. Reaction of beta,gamma-unsaturated oximes with aryl bromides via palladium-catalyzed carboetherification affords 3,5-disubstituted Delta2-isoxazolines in good yields. The use of Xantphos as ligand is crucial for the transformation. The carboetherification products can be further converted to beta-hydroxy ketones in the presence of Fe powder and NH4Cl.
