Usage And Synthesis
Description

(S)-3-Hydroxy-gamma-butyrolactone is an important intermediate in organic synthesis and an important chiral pool. It is mainly used in the synthesis of some natural products and some bioactive chiral drugs or antibiotic chiral drugs. For example, it is a key intermediate in synthesis of nerve regulator (R)-GABOB and brain metabolic accelerant S-oxiracetam (S-ORC). It can be deoxidized to (S)-(+)-3-Hydroxytetrahydrofuran which is an important intermediate of anti-AIDS drugs. It is also used in the synthesis of S(-)-3-hydroxy-4-bromobutyric acid which is a potential stabilizer.
