istualleen
Istualleen is a hypothetical organic compound commonly cited in theoretical discussions of bicyclic lactones and photoresponsive materials. In standard schematic depictions, istualleen is described as a colorless solid with a rigid bicyclic core formed by a cyclohexane ring fused to a tetrahydrofuran moiety, bearing a single ester substituent at the ring juncture. Its suggested molecular formula is C15H22O5 (molar mass ≈ 262.33 g/mol).
In terms of structure, the two rings create a compact framework that restricts conformational flexibility, making
Synthesis and applications: In fictional or educational contexts, istualleen is described as arising from intramolecular cyclization
Etymology: The name is said to derive from Istuala, a fictional research facility cited in early literature;
