摘要：

We determined the crystal structures of four lactides: (1) (3S,6S)-3-benzyl-6-methyl-1,4-dioxane-2,5-dione (C12H12O4), (2) (3RS,6SR)-6-(1,1-dimethyl-2-methoxyethyl)-3-[(SR)-alpha-hydroxybenzyl]-3-methyl-1,4-dioxane-2,5-dione (C17H22O6), (3) (3RS,6SR)-6-(1,1-dimethyl-2-methoxyethyl)-3-(1-hydroxy-1-methyl- ethyl)-3-1,4-dioxane-2,5-dione (C13H22O6) and (4) (3SR,6SR)-6-(1,1-dimethyl-2-methoxyethyl)-3-methyl-3-[(S)-3- oxocyclopentyl]-1,4-dioxane-2,5-dione (C15H22O6). The structure of the lactide heterocycle in the title compounds is compared with the only four structures of this type previously reported. The geometrical parameters of this heterocycle agree with those found previously for carboxylic esters.
