(S)-2-(2-OXOPYRROLIDIN-1-YL)PROPANOIC ACID

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Following the procedures of Examples 1C-1E, α(S)-methyl-2-oxo-1-pyrrolidineacetic acid was first alkylated with ethyl iodide and then with benzylmercaptomethyl bromide. Removal of the benzyl group in the usual way and purification by chromatography provided the title compound as a mixture of diastereomers. [α]D25 =-4.04° (c=1, methanol).
