1-Bromoacetyl-2,6-bis(4-methoxyphenyl)-3,5-dimethylpiperidin-4-one
Abstract
In the title compound, C23H26BrNO4, the piperidinone ring adopts a boat conformation. The dihedral angle between the two benzene rings is 70.9 (1)°. The two methoxy groups are close to coplanar with the attached benzene rings [C—C—O—C torsion angles of 6.3 (5) and 16.4 (4)°]. A weak C—H...Br intramolecular interaction is observed. In the crystal structure, molecules are linked into a chain along [101] by intermolecular C—H...O hydrogen bonds. A short intermolecular Br...O contact [3.063 (2) Å] is observed.
