General description

2-Methyl-1-pyrroline, a monocyclic imine, is a pyrroline derivative. It is a five-membered heterocyclic compound having various biological and pharmacological applications. It is formed during the Rh(I) complexes (containing N,N-donor ligands and N,P-donor ligand) immobilized on glassy carbon electrode surfaces catalyzed intramolecular hydroamination of 4-pentyn-1-amine. It reacts with with 2-oxopropanal to afford acetyl-1-pyrroline (AP).

Application

2-Methyl-1-pyrroline (2-MPN) may be used in the enantioselective enzymatic synthesis of (R)- and (S)-2-methylpyrroline in the presence of whole-cells catalysts isolated from Strptomyces sp. strains GF3587 and GF3546 respectively.
