Descrição

Descrição geral

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

Aplicação

(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.
