Alkaloids with partial pyrrolidine structure are usually sub-categorized based on their occurrence and biogenetic origin. Hygrin and cuscohygrin were isolated from the leaves of the coca shrub, [2] while (-)-codonopsinine was isolated from the woodland vine tiger bell.
Pyrrolidine, also known as tetrahydropyrrole, is an organic compound with the molecular formula (CH 2) 4 NH. It is a cyclic secondary amine, also classified as a saturated heterocycle.
2-Pyrrolidone, also known as 2-pyrrolidinone or butyrolactam, is an organic compound consisting of a 5-membered lactam, making it the simplest γ-lactam.It is a colorless liquid that is miscible with water and most common organic solvents.
N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam.It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents.
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.
The dextrorotary (R)-(+)-enantiomer is the more pharmacologically active, although a variety of related derivatives have been studied.[2]Side effects including chest pain (suggestive of possible cardiovascular toxicity) have been seen following recreational use of diphenylprolinol, although it was combined with glaucine in a party pill product, thus making it impossible to say for certain ...
