Gonane is a tetracyclic hydrocarbon with no double bonds. It is formally the parent compound of the steroids, hence it is called the "steroid nucleus". [1] [4] [5] Some important gonane derivatives are the steroid hormones, characterized by methyl groups at the C10 and C13 positions and a side chain at the C17 position.
Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) with formula C 14 H 10, consisting of three fused benzene rings. It is a colorless, crystal-like solid, but can also appear yellow. Phenanthrene is used to make dyes, plastics, pesticides, explosives, and drugs. It has also been used to make bile acids, cholesterol and steroids. [3]
The three cyclohexane rings (A, B, and C in the first illustration) form the skeleton of a perhydro derivative of phenanthrene. The D ring has a cyclopentane structure. When the two methyl groups and eight carbon side chains (at C-17, as shown for cholesterol) are present, the steroid is said to have a cholestane framework. The two common 5α ...

Nudol is a phenanthrene from the orchids Eulophia nuda, Eria carinata and Eria stricta. [10] 9,10-Dihydro-2,5-dimethoxyphenanthrene-1,7-diol is a phenanthrene from Eulophia nuda. This compound shows cytotoxic activity against human cancer cells. [11] 2,7-Dihydroxy-3,6-dimethoxyphenanthrene is a phenanthrene from Dehaasia longipedicellata. [12]
Cyclopentanone is common precursor to fragrances, especially those related to jasmine and jasmone.Examples include 2-pentyl- and 2-heptylcyclopentanone. [4] It is a versatile synthetic intermediate, being a precursor to cyclopentobarbital.
