Application

N-Methylpyrrolidine can be used as a starting material to synthesize:
N-methyl pyrrolidine-zinc borohydride (ZBHNMP), a reducing agent for reduction of aldehydes, ketones, acid chlorides, and esters. ZBHNMP is also used in the reductive amination of aldehydes and ketones to their corresponding amines.
N-alkyl-N-methyl-pyrrolidinium bis(trifluoromethanesulfonyl)imide ionic liquids.
N-methylpyrrolidine-2-one hydrotribromide applicable as a catalyst for aziridination of alkenes.

The 42-residues beta-(1-42) peptide is the major protein component of amyloid plaque cores in Alzheimer's disease. In aqueous solution at physiological pH, the synthetic beta-(1-42) peptide readily aggregates and precipitates as oligomeric beta-sheet structures, a process that occurs during amyloid
