M. Niemeyer and M. Gan

Abstract: In the crystalline state, the molecule of the title compound, (+)-(1R,4R)-3-(hydroxybenzylidene)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-one, C₁₇H₂₀O₂, exists in the enolized form, with the H atom located on the phenyl-substituted C-O fragment rather than on the camphoryl-substituted one. The enolic H atom is involved in intramolecular hydrogen bonding [OO = 2.633  (2)  Å].
