organic compounds
In the title compound, C19H21BrN2O2S, the fused pyrrolidine rings adopt envelope conformations. The molecular packing is stabilized by weak intermolecular C—HO interactions and van der Waals forces.
organic compounds
The title compound, C25H31NO2, crystallizes with two molecules in the asymmetric unit. In both molecules, the central dihydropyridine ring adopts a flattened boat conformation. In molecule A, the outer rings adopt sofa conformations, whereas in molecule B, one of the outer rings is disordered and the other ring adopts a sofa conformation. In the crystal structure, C—HO interactions link the molecules to form a tape that runs along the b axis.
