2-[(1R*,4R*)-1,4-Dihy-droxy-cyclo-hex-yl]acetic acid
Abstract:
The title compound, C(8)H(14)O(4), is an isolation product of the aerial parts of Senecio desfontanei. The acetic acid group is oriented at a dihedral angle of 48.03 (9)° with respect to the basal plane of the cyclo-hexane-1,4-diol chair. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring with an envelope conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, resulting in R(3) (3)(20) ring motifs and C(2) O-H⋯O-H⋯O-H⋯ chains. Overall, a three-dimensional polymeric network arises. A C-H⋯O contact is also present.

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.
IUPAC Nomenclature of Carboxylic Acids
For acyclic saturated monocarboxylic acids, the longest hydrocarbon chain containing the –COOH carbon is identified as the parent chain. Then, the last -e of the parent hydrocarbon name is replaced with a suffix -oic acid.

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.
