| Physical and Chemical Properties | (s)-3-hydroxy-gamma butyrolactone is a colorless liquid, soluble in water, alcohol and other organic solvents, insoluble in petroleum ether, etc., it is a very important organic synthesis intermediates, it is also a very important source of chirality. Mainly used as a key intermediate of Modulator (R)-gamma-hydroxy-beta-Q hydroxybutyric acid [(R)-GABOB],(R)-GABOB is used to treat hyperlipidemia;(s)-Oxiracetam is a promoter of brain metabolism, but also its synthesis; Its reduction can be obtained (s)-3-hydroxytetrahydrofuran, which is an important intermediate for the treatment of AIDS drugs; the (s)-3-hydroxy-4-bromobutyric acid synthesized from it is a potential stabilizer; It is converted into (s)-5-hydroxymethyl-1, 3-oxazolin-2-one available for the latest generation of antibacterial drugs; In addition,(s)-n-methyl-3-hydroxypyrrole and (R)--N-methyl -3-methyl-pyrrole also has important physiological activity, can also be obtained by simple conversion of (s)-3-hydroxy-gamma butyrolactone. Many natural products can also be synthesized from (s)-3-hydroxy-γbutyrolactone. |
