(R)-3-Hydroxypyrrolidine Chemical Properties,Usage,Production
Chemical Properties
clear yellow to orange-brown viscous liquid
Uses
(R)-Pyrrolidin-3-ol is used in preparation of allosteric BCR-ABL bifunctional proteolysis targeting chimera compounds.
Synthesis
51-35-4
40499-83-0
The general procedure for the synthesis of 3-hydroxypyrrolidine from L-hydroxyproline is as follows: Example 1: Synthesis of (R)-3-pyrrolidinol To a 1 liter reaction vessel was added (4R)-hydroxy-L-proline (250 g, 1.907 mol), 2-cyclohexen-1-one (18.3 g, 0.1907 mol), and polyethylene glycol (750 mL, 400 average molar mass). The reaction was carried out by stirring the mixture under nitrogen protection at 150-160 °C. After 10 h, the reaction was judged complete when the reaction mixture changed from a suspension to a homogeneous phase. The yield of (R)-3-pyrrolidinol was 89.3% as determined by gas chromatographic analysis. Subsequently, the reaction solution was subjected to decompression distillation at the same temperature to collect fractions with boiling points of 100-120 °C (pressure 6-40 hPa) to give (R)-3-pyrrolidinol (120.4 g, 72.5% yield, 99.6% chemical purity, 99.9% optical purity ee).
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.
