Dioxolane

Dioxolane or 1,3-dioxolane is an heterocyclic acetal with the chemical formula C3H6O2. It is an analogue of tetrahydrofuran with an additional ring oxygen atom and an analogue of the 6 membered ring 1,3-dioxane. The isomeric 1,2-dioxolane analogue is classified as a peroxide. Dioxolane is used as a solvent and as a co-monomer in polyacetals.

Dioxolanes are a group of organic compounds sharing the dioxolane ring structure. Dioxolanes can be prepared by acetalization of carbonyl groups with ethylene glycol. (+)-cis-Dioxolane is the trivial name for L-(+)-cis-2-methyl-4-trimethylammoniummethyl-1,3-dioxolane iodide which is a muscarinic acetylcholine receptor agonist.
