Facile synthesis of (R)-4-mercaptopyrrolidine-2-thione from l-aspartic acid

An SN2-type of substitution of (S)-bromide 4, which had been prepared from L-aspartic acid, with potassium thiobenzoate provided (R)-benzoylthio derivative 5 with complete inversion of the configuration. Compound 5 was converted, via iodide 6c, to (R)-4-a
