Application: Pyrrolidine can be used as:
• A base for the chemoselective reduction of ketones to alcohol in the presence of decaborane and cerium(III) chloride heptahydrate in methanol.
• A reactant with benzaldehyde and β-naphthol for the synthesis of betti base using non-ionic surfactant (Triton X-100) as a catalyst.
• A catalyst in the synthesis of aldimines from aldehydes and primary amines.
• A modifier for aluminum hydride reagent, which is used as a selective reducing agent to transform N-benzyl-4-ethoxycarbonylpiperidine into N-benzyl-4-formylpiperidine.
• As a solvent/base in palladium-catalyzed Sonagashira coupling reactions.
