ABSTRACT: In the title compound, C21H21BrClNO4, the dihydro-pyridine ring adopts a flattened boat conformation. The 3-bromo-5-chloro-2-hy-droxy-phenyl ring forms a dihedral angles of 84.44?(7)° with the dihydro-pyridine mean plane. The mol-ecular conformation is stabilized by an intra-molecular O-H?O hydrogen bond, with an S(8) ring motif. In the crystal, O-H?O and C-H?O hydrogen bonds link the mol-ecules, forming a three-dimensional network.

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.
