Usage of Pyrrolidine CAS 123-75-1

Pyrrolidine CAS 123-75-1 is used as building block in the synthesis of organic compounds. It is used to activate ketones and aldehydes toward nucleophilic addition. It is also utilized in promoting aldol condensation of ketones and aldehydes by forming enamine.

Why is pyrrolidine important in pharma?

Pyrrolidine motif has been employed to improve a drug’s potency, selectivity, and pharmacokinetic profile. As a natural amino acid, proline is ubiquitous as a building block in enzymes, receptors, ion channels, and endogenous ligands. Not surprisingly, some drugs derived from nature contain the proline moiety as well.

What is the difference between pyrrole and pyrrolidine?

pyrrolidine does not have any double bonds while pyrrole has them. As a result, pyrrole is an aromatic compound which limits the availability of the lone pair of electrons on the nitrogen for bonding with electrophiles.
