Pyrrolines are formally derived from the aromate pyrrole by hydrogenation. 1-Pyrroline is a cyclic imine while 2-pyrroline and 3-pyrroline are cyclic amines. 1-Pyrroline 2-Pyrroline 3-Pyrroline Substituted pyrrolines 2-Acetyl-1-pyrroline, an aroma compound with a white bread-like smell Thienamycin, a beta-lactam antibi… (More on Pyrroline)
