title: 10-(2-Hy-droxy-eth-yl)-9-(2-hy-droxy-phen-yl)-3,3,6,6-tetra-methyl-1,2,3,4,5,6,7,8,9,10-deca-hydro-acridine-1,8-dione.
abstract: The dihydro-pyridine ring in the title compound, C(25)H(31)NO(4), adopts an envelope conformation with the methine C atom representing the flap. The cyclo-hexenone rings also adopt envelope conformations with the C atoms bearing the methyl C atoms representing the flaps. The phenolic hy-droxy group forms an intra-molecular hydrogen bond to one of the two keto O atoms. The hy-droxy group of the N-bonded alkyl chain forms an inter-molecular hydrogen bond to the other keto O atom of an adjacent mol-ecule. The latter hydrogen bond leads to the formation of a helical chain running along the b axis.
