1-(2-Hy-droxy-eth-yl)pyrrole-2,5-dione.

ABSTRACT: The asymmetric unit of the title compound, C(6)H(7)NO(3), contains two mol-ecules (A and B) related by a non-crystallographic twofold pseudo-axis. The mol-ecules are joined in the (AABB)(n) manner by O-H⋯O hydrogen bonds between their hy-droxy groups, thus forming C(2) chains along the a-axis direction. Neighboring mol-ecules of the same kind (A and A, or B and B) are related by inversion centers, so that all hy-droxy H atoms are disordered other two sets of sites with half occupancies (superimposed O-H⋯O and O⋯H-O fragments). The mol-ecules are further linked by C-H⋯O inter-actions, which can be considered to be weak hydrogen bonds.

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.

Project description: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.
