clear colorless to yellow liquid | [Uses]
2-Methyl-1-pyrroline acts as monocyclic imine. It is a pharmaceutical intermediate. | [Definition]
ChEBI: A member of the class of pyrrolines that is 1-pyrroline substituted at position 2 by a methyl group. | [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). |
