Description General description (S)-(-)-α,α-Diphenyl-2-pyrrolidinemethanol is a bifunctional organocatalyst. 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. Packaging 1, 5 g in glass bottle
