3,3-Dimethyl-10-(4-methoxy-phen-yl)-9-(4-nitro-phen-yl)-1,2,3,4,5,6,7,8,9,10-deca-hydro-acridine-1,8-dione
Abstract:
The title compound, C(28)H(28)N(2)O(5), consists of a partially hydrogenated acridine ring system with two substituted phenyl substituents on the dihydro-pyridine ring which are both nearly perpendicular to the mean plane of the acridine unit [dihedral angles of 81.3 (1) and 89.6 (1)° between the central ring of acridine and the methoxyphenyl and nitrophenyl rings, respectively]. The dihydro-pyridine ring is almost planar, whereas both the outer unsymmetrical six-membered rings adopt half-chair conformations.

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
Adrenergic Agonists: Chemistry and Structure-Activity Relationship
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.

Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
