The Difference Between γ-Butyrolactone and Butyrolactone：

What is the difference between γ-Butyrolactone and Butyrolactone? Welinks tells you:

gamma-Nonanolactone is also called 4-Hydroxynonanoic acid gamma-lactone. The product names are: alphs-pentyl-gama-butyrolactone; propyl-nonanolactone; coconut aldehyde, etc. Butyrolactone is a high boiling point solvent with good performance, strong solubility, good electrical properties, high stability, non-toxic and safe to use. It has a wide range of applications in petrochemical, pharmaceutical, pesticide and other fields.

Main functions and uses of γ-butyrolactone: γ-butyrolactone is a colorless liquid, soluble in water, alcohol and other organic solvents, and insoluble in petroleum ether. It is a very important intermediate in organic synthesis and a very important source of chirality. It is mainly used as the key intermediate of regulator (R)-γ-hydroxy-β-Q hydroxybutyric acid [(R)-GABOB]. (R)-GABOB is used to treat hyperlipidemia. (s)-Oxiracetam is a booster of brain metabolism and is also synthesized. It can be reduced to obtain (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. Convert it into (s)-5-hydroxymethyl-1,3-oxazolin-2-one to obtain the latest generation of antibacterial drugs. In addition, (s)-N-methyl-3-hydroxypyrrole and (R)-N-methyl-3-methylazopyrrole also have important physiological activities, and γ-butyrolactone can also be produced by simple conversion And get. Many natural products can also be synthesized from gamma butyrolactone.
