Pyrrolines, also known under the name dihydropyrroles, are three different heterocyclic organic chemical compounds that differ in the position of the double bond. Pyrrolines are formally derived from the aromate pyrrole by hydrogenation. 1-Pyrroline is a cyclic imine, whereas 2-pyrroline and 3-pyrroline are cyclic amines. == Substituted pyrrolines == * 2-Acetyl-1-pyrroline, an aroma compound with a white bread-like smell * Thienamycin, a beta-lactam antibiotic * MTSL, a chemical used for certain NMR experiments * Pyrrolysine, an unusual proteinogenic amino acid * 1-Pyrroline-5-carboxylic acid, a biosynthetic metabolite * Porphyrin, consisting of two alternating pairs of pyrrol and pyrroline connected via methine (=CH-) bridges == Spermous == In the interests of descriptive accuracy and possible biological significance (see below) we are adopting the name "spermous" for the new primary odor epitomized by 1-pyrroline.〔J.
