Pyrroline

Pyrroline

Pyrrolines, also known under the name dihydropyrroles, are three different heterocyclic organic chemical compounds which differ in the position of the double bond. 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.

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
* 1-Pyrroline-5-carboxylic acid, a biosynthetic metabolite
* Porphyrin, consisting of two alternating pairs of pyrrol and pyrroline connected via methine (=CH-) bridges

See also

* Pyrrol, the aromatic analog with two double bonds
* Pyrrolidine, the fully saturated analog without double bonds
