11-[3-(Dimethyl-amino)prop-yl]-6,11-dihydro-dibenzo[b,e]thiepin-11-ol
Abstract:
There are two independent mol-ecules (A and B) in the asymmetric unit of the title compound, C(19)H(23)NOS. In each mol-ecule, the seven-membered thiepine ring is bent into a slightly twisted V-shape. The dihedral angles between the mean planes of the two benzene rings fused to the thiepine ring are 75.7 (5) in mol-ecule A and 73.8 (4)° in mol-ecule B. In both mol-ecules, an intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, weak inter-molecular C-H⋯O and C-H⋯π-ring inter-actions are observed.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
