✦ Synopsis

In the title compound, C 15 H 17 NO 2 , the six-membered cyclohexene ring has an envelope conformation. The structure is stabilized by O-HÁ Á ÁN hydrogen bonds and weak van der Waals interactions. There are no C-HÁ Á Á orinteractions between the two ring systems; however, there is an intermolecular C-HÁ Á ÁO hydrogen bond.
