CAS 127913-44-4: (S)-(-)-4-chloro 3-hydroxybutyronitrile

(S)-4-Chloro-3-hydroxybutyronitrile (CHB) is a synthetic chemical that is used as a feedstock in the manufacture of pleuromutilin derivatives. CHB has been shown to be an effective inhibitor of bacterial growth, with a wide range of activity against both Gram-positive and Gram-negative bacteria. This chemical can be prepared from chloropropane and sodium hydroxide in two steps with a yield of about 73%. Stereoselective synthesis was carried out using microcapsules to produce (S)-4-chloro-3-hydroxybutyronitrile. This process is economical and environmentally friendly because it does not require the use of hazardous reagents such as hydrogen chloride gas or sodium hydroxide solution.

(S)-4-Chloro-3-hydroxybutyronitrile

Applications (3S)-4-Chloro-3-hydroxybutyronitrile is used in various organic precursor syntheses. It is used in the synthesis of hydroxypyrrolidinones to by used as carbapenem precursors. Also used in the preparation of atorvastatin (A791750) precursors. Impurity in the synthesis of Rosuvastatin (R700500), a selective, competitive HMG-CoA reductase inhibitor. Antilipemic.
