8-[(2-Hy-droxy-phen-yl)imino]-3,5a,9-trimethyl-3a,4,5,5a,8,9b-hexa-hydro-naphtho-[1,2-b]furan-2(3H)-one.
The title compound, C(21)H(23)NO(3), is a phenyl-imine derivative of the well known anthelmintic agent α-santonin. The trans-fused cyclo-hexane and γ-lactone rings of the α-santonin ring system adopt chair and envelope conformations, respectively, whereas the hexa-diene ring is approximately planar [maximum deviation = 0.029 (4) Å] and forms a dihedral angle of 62.30 (11)° with the benzene ring. An intra-molecular O-H⋯N hydrogen bond is observed.
