The dihydropyridine ring in the title compound, C26H 32BrNO4, adopts an envelope conformation with the methine C atom representing the flap. The cyclohexenone rings also adopt envelope conformations. The phenolic hydroxy group forms an intramolecular hydrogen bond to one of the two keto O atoms. Intermolecular weak C-H⋯O hydrogen bonding is present in the crystal structure. The hydroxypropyl group is disordered over two sets of sites with an occupancy ratio of 0.636 (6):0.364 (6).
