(S)-(-)-α,α-Diphenyl-2-pyrrolidinemethanol Chemical Properties,Usage,Production

Chemical Properties

white to beige crystals or crystalline powder

Uses

suzuki reaction

Uses

(S)-(-)-α,α-Diphenyl-2-pyrrolidinemethanol is used to prepare the corresponding oxazaborolidines for the borane-mediated asymmetric reduction of ketones.

Preparation

Into a four-necked flask, add tetrahydrofuran, L-proline methyl ester hydrochloride, and phenyl magnesium chloride (dissolved in tetrahydrofuran) solution was added dropwise from a constant pressure dropping funnel, and the addition was completed in about 4 hours, and then stirred at 10-15°C for 3 hours. Add water, adjust the pH to 5-6 with 10% ammonium chloride aqueous solution, extract with dichloromethane, extract the aqueous layer twice with dichloromethane each time, and obtain the organic phase. Wash once with saturated sodium chloride aqueous solution. The organic phase was dried with anhydrous sodium sulfate for 4 hours and filtered. The obtained organic phase was distilled under reduced pressure to distill dichloromethane and tetrahydrofuran to obtain light yellow oily (S)-(-)-α,α-Diphenyl-2-pyrrolidinemethanol, yield 86.6%.

Application

(S)-(+)-α,α-Diphenyl-2-pyrrolidinemethanol (DPPM) may be used in the following processes:

  • DPPM reacts with catecholborane to form a spiroborate ester, which can be an efficient catalyst for the synthesis of enantiopure alcohols by borane reduction of acetophenone.
  • The catalyst generated in situ by reacting DPPM with borane-diethylaniline, can efficiently catalyze the enantioselective reduction of 2′-fluoroacetophenone.
  • Mesoporous SBA-15 silica functionalized with DPPM can catalyze the addition of diethylzinc to benzaldehyde to form (S)-1-phenyl-propanol.
Used to prepare the corresponding oxazaborolidines for the borane-mediated asymmetric reduction of ketones.

General Description

(S)-(-)-α,α-Diphenyl-2-pyrrolidinemethanol is a bifunctional organocatalyst.
