The number of known asymmetrically substituted hemilactides, important precursors for obtaining regular derivatives of polylactide polymers, is still limited and structural characterization of most of them is incomplete. In the title racemic 1,4-dioxane-2,5-dione derivative, C<sub>9</sub>H<sub>10</sub>O<sub>5</sub>, the hemilactide heterocycle exhibits a twist-boat conformation. The bulkier propynyloxymethyl group is in an axial position with a <i>gauche</i> conformation for the CH<sub>2</sub>-O ...[more]
