Introduction | (S)-tert-leucine is a white solid, which can be obtained by reducing carboxyl groups from L-tert-leucine. The reducing agent can be selected From sodium borohydride and lithium tetrahydroaluminum. |
preparation | add (83.04g,4eq) sodium borohydride, 2L dried tetrahydrofuran, L-tert-leucine 120g into a 5L three-mouth flask. Under the protection of nitrogen balloons, 760mL of 4 hydrofuran solution of iodine (231g,1eq) is slowly dropped in an ice bath at 0 ℃ to make it fully react. After dropping and stirring until no gas is released, then heat and reflux for 18 hours, cool to room temperature, and slowly drop 300ml of methanol to clarify the mixture. Stir for 30min to remove the white paste from the solvent, and then dissolve it in 800mL 20% KOH. In solution. The room temperature solution was stirred for 4h, and extracted with 1.5L dichloromethane 3 times each time, the organic phase was combined, washed with saturated salt water, dried with anhydrous sodium sulfate and concentrated by spin evaporation to obtain white semi-solid 97g yield 90%. |
