| | (S)-3-Hydroxypyrrolidine Usage And Synthesis |
| Description | (S)-3-Hydroxypyrrolidine is a chiral organic compound that serves as an important building block in the synthesis of various pharmaceuticals and natural products. It is a four-membered heterocyclic amino alcohol, featuring a hydroxyl group and a stereogenic center. The 'S' prefix indicates the configuration at the stereocenter, which is crucial for its reactivity and biological activity. This compound is notable for its role as an intermediate in the synthesis of drugs, particularly those targeting the central nervous system. The enantiomeric purity of (S)-3-Hydroxypyrrolidine is often critical, as the 'R' and 'S' enantiomers can exhibit different pharmacological properties. | | Chemical Properties | clear light yellow to yellow liquid after melting | | Uses | (S)-(-)-3-Hydroxypyrrolidine is an important raw material and intermediate used in organic synthesis, pharmaceuticals agrochemicals and dyestuff fields. | | Purification Methods | The (±)-isomer is purified by repeated distillation ( b 102-104o/12mm, 108-110o/18mm), and the (±)-picrate crystallises from EtOH with m 140-141o. The R(+)-enantiomer has b 70o/0.6mm and [] D +5.6o (c 3.63, MeOH). Its hydrochloride has a negative rotation and its dimethiodide has m 230o and [] 24 -8.02o.
