Diastereoselective methylation of dimethyl (S)-malate 7, followed by two, three-step reductive de-hydroxylation procedures afforded dimethyl (R)-2-methylsuccinate 11 in 80.2% e.e. and 84.7% e.e., respectively. The latter compound was further transformed into the natural enantiomers of the ant venom alkaloids (R)-leptothoracine 1 and (R)-3-methyl-N-(2-phenylethyl)-pyrrolidine 2.
