[Chemical Properties]

1,4-Dioxaspiro[4.5]decan-8-one is white to beige crystalline powder or crystals
[Uses]

1,4-Dioxaspiro[4.5]decan-8-one(4746-97-8) is used in the preparation of series of potent analgesic compounds. 1,4-Cyclohexanedione Monoethylene Acetal is also used as a building block in the synthesis of tritium labelled probes for the autoradiography study of the dopamine reuptake complex.
[Uses]

Intermediates of Liquid Crystals
[Application]

1,4-Dioxaspiro[4.5]decan-8-one(4746-97-8) can be used:
(1) Used in a study of microwave-assisted reductive amination.
(2) Via a novel aromatization process, this bicyclic frame can be converted into a series of 5-alkoxytryptamine derivatives including serotonin, melatonin and bufotenin.
[Purification Methods]

Recrystallise it from pet ether. It sublimes slowly on attempted distillation. Also purify it by dissolving it in Et2O and adding pet ether (b 60-80o) until turbid and cooling. [Gardner et al. J Am Chem Soc 22 1206 1957, Britten & Lockwood J Chem Soc Perkin Trans 1 1824 1974.] [Beilstein 19/4 V 93.]
