    摘要: (-)-Dimethyl 2-cyano-2-methylsuccinate ((-)-IIIa) was synthesized from menthyl cyanoacetate((-)-I), and the absolute configuration of which was elucidated as (S)-configuration by chemical correlation to the known (R)(+)-β-methylterbic acid ((R)(+)-VII). (-)-Dimethyl 2-carbanmoyl-2-methylsuccinate ((-)-IV) are also (-)-methyl 3-methyl-2, 5-dioxo-3-pyrrolidincearboxylate ((-)-V) are also confirmed as belonging to (S)-configuration and (+)-3-(1-hydroxy-1-methylethyl)-3-methyl-2, 5-prrolidineedione((+)-VI) is belonging to (R)-configuration. Preliminary experiments on racemic compounds are also described.
