(1,5E,11E)-Tridecatriene-7,9-diyne-3,4-diacetate, with the CAS number 201012-14-8 and molecular formula C₁₇H₁₆O₅, is a distinctive polyacetylene derivative belonging to the class of natural product-like compounds. Its molecular weight is 300.31, and it typically presents as an oily substance under standard conditions.
This compound is not only a synthetically valuable target but also has natural origins—it can be extracted from Atractylodes lancea, a plant known for its rich content of bioactive secondary metabolites. Structurally, it features a unique combination of three double bonds (configured as 1, 5E, 11E) and two triple bonds (at the 7 and 9 positions) in its 13-carbon backbone, along with two acetate groups at the 3 and 4 positions. This structural arrangement classifies it as a member of the polyacetylene family, which is widely recognized for diverse biological activities in natural product chemistry.
Notably, while it has a primary systematic name, some sources may reference it with truncated or variant labels such as "9-diyne-3" or "4-diacetate," though these are not formal aliases. The most commonly used and accepted designation remains its full IUPAC name: (1,5E,11E)-tridecatriene-7,9-diyne-3,4-diacetate.
