6-Benzyl-3-(1,4-dioxaspiro[4.5]decan-2-yl)-8,8-dimethyl-1-oxa-2,6-diazaspiro[4.4]non-2-ene-7,9-dione

Abstract

In the title compound, C23H28N2O5, the 4,5-dihydroisoxazole ring adopts a slight envelope conformation and the dioxolane ring is in a twisted conformation. The molecular structure, in the vicinity of the benzyl group, may be influenced by an intramolecular C—H...O hydrogen bond which generates an S(7) ring motif. In the crystal structure, molecules are linked via weak intermolecular C—H...O hydrogen bonds, forming extended chains along the b axis. Further stabilization is provided by weak C—H...π interactions.
