title: 6-Benzyl-3-(1,4-dioxaspiro-[4.5]decan-2-yl)-8,8-dimethyl-1-oxa-2,6-diaza-spiro-[4.4]non-2-ene-7,9-dione.
abstract: In the title compound, C(23)H(28)N(2)O(5), the 4,5-dihydro-isoxazole ring adopts a slight envelope conformation and the dioxolane ring is in a twisted conformation. The mol-ecular structure, in the vicinity of the benzyl group, may be influenced by an intra-molecular C-H⋯O hydrogen bond which generates an S(7) ring motif. In the crystal structure, mol-ecules are linked via weak inter-molecular C-H⋯O hydrogen bonds, forming extended chains along the b axis. Further stabilization is provided by weak C-H⋯π inter-actions.
