Pyrroline
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.

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.[1]
