Reactions of(4S,5R)-1-(3,4-Dimethyl-2-oxo-5-phenylimidazolidine)carbonyl-isocyanate (4) with appropriate Baylis-Hillman adducts 5 gave the corresponding acyl carbamates 6,7 as equimolar diastereomeric mixtures. These mixtures were treated with DABCO, to afford with moderate diastereoselection easily separable [2-(3",4"-dimethyl-2"-oxo-5"-phenylimidazolidine-1-carboxamido)(aryl)methyl]acrylates ...

The title mol-ecule, C(17)H(15)NO(2), is twisted, the dihedral angle between the terminal benzene rings being 63.30 (6)°. In the crystal, C-H⋯O and C-H⋯N inter-actions lead to supra-molecular layers in the ab plane. These are connected along the c axis via C-H⋯π inter-actions.
