چکیده
In the title compound, C(15)H(12)ClNO, the isoxazoline ring adopts an envelope conformation with the C atom bearing an unsubstituted phenyl ring as the flap atom. The chlorinated phenyl group is nearly in-plane with the four coplanar atoms of the heterocycle and the corresponding mean planes enclosing an angle of 1.16 (7)°. The unsubstituted phenyl group attached to the envelope flap atom approaches a nearly perpendicular orientation relative to the isoxazoline ring with a dihedral angle of 74.93 (7)°. In the crystal, weak C-H⋯O, C-H⋯N and C-H⋯π inter-actions connect the mol-ecules into layers perpendicular to the a axis.

2-Phenyl-4-alkyl-4-hydroxymethyl-1,3-oxazolones (2a-d) have been identified as side products accompanying activation of N-benzoyl-2-alkylserines (1a-d). Oxazolones 2a-d in the presence of amine rearrange subsequently to corresponding 4-alkyl-2-phenyl-4,5-dihydro-1,3-oxazole-5 carboxylic acids (4a-d) at a 20-68% yield.
