Definition
ChEBI: 3-pyrroline is a pyrroline.
General Description
Various 3-pyrrolines (2,5-dihydropyrroles) have been synthesized by two-step reaction sequence of alkylation/alkylidene carbene CH-insertion reaction. Synthesis of 3-pyrroline has been reported by employing cis-1,4-dichloro-2-butene as starting reagent.
