  2. Cyclopentanone - Wikipedia

    en.wikipedia.org/wiki/Cyclopentanone

    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. [5] Cyclopentobarbital, a drug made from cyclopentanone

  3. Cyclopentenone - Wikipedia

    en.wikipedia.org/wiki/Cyclopentenone

    2-Cyclopentenones can be synthesized in a number of ways. One of the routes involves elimination of α-bromo-cyclopentanone using lithium carbonate [2] and Claisen condensation-decarboxylation-isomerization cascades of unsaturated diesters as shown below. [3] Industrial synthesis of cyclopentenone

  4. Cyclopentane - Wikipedia

    en.wikipedia.org/wiki/Cyclopentane

    Cyclopentane (also called C pentane) [4] is a highly flammable alicyclic hydrocarbon with chemical formula C 5 H 10 and CAS number 287-92-3, consisting of a ring of five carbon atoms each bonded with two hydrogen atoms above and below the plane.

    For instance, the reaction of cyclopentanone with diazomethane forms cyclohexanone (shown below). The Büchner ring expansion reactions utilizing diazoalkanes have proven to be synthetically useful as they can not only be used to form 5- and 6-membered rings, but also more unstable 7- and 8-membered rings. [27]
