The pyrrolidine ring is the central structure of the amino acids, proline and hydroxyproline. The pyrrolidine ring structure is present in numerous natural alkaloids such as nicotine and hygrine and is found in many pharmaceutical drugs such as procyclidine and bepridil. It also forms the basis for the racetam compounds (e.g. piracetam, aniracetam). Pyrrolidine is a strong basic compound and is soluble in most organic solvents. Pyrrolidine is a clear liquid with an unpleasant ammoniacal, fishy, shellfish-like taste and seaweed-like odor ( http://www.thegoodscentscompany.com/data/rw1009391.html). Pyrrolidine is found naturally in the leaves of tobacco and carrot. Pyrrolidine is present in bread, milk, cheese, carrots, celery stalks, beer, spirits, coffee, caviar, and fatty fish. Pyrrolidine is a flavouring agent added in trace amounts to chewing gum, soft candy, and non-alcoholic beverages (RoutledgeHandbooks-9781439847503-chapter3.pdf). Pyrrolidine is widely distributed in foodstuffs in trace amounts, presumably as a bacterial decarboxylation product of proline Pyrrolidine is a metabolite of the gram-negative bacterium, Xenorhabdus (PMID: 19598185).
