标题盐(S)-(R)-2-carboxymethyl-5-oxofuran-2-carboxylate，C8H12N+·C7H7O6−是通过拆分外消旋的内酯混合物作为非对映盐来分离R-阴离子的，R-阴离子是由内酯环2-位上的羧酸基失去一个质子而形成的。晶体结构的堆积指数为69.5%，表明堆积非常有效。
The title salt, (S)-α-methylbenzylammonium (R)-2-carboxymethyl-5-oxofuran-2-carboxylate, C8H12N+·C7H7O6−, was crystallized by resolution of a racemic mixture of lactones as the diastereomeric salt to separate the R anion, which is formed by the loss of a proton from the carboxylic acid group on the 2-position of the lactone ring. The crystal structure has a packing index of 69.5%, indicating very efficient packing.
