Uses: Pyrrolidine is a flammable alkaline liquid that undergoes reactions typical of secondary amines. It is used to prepare pesticides and rubber accelerators and as a chemical intermediate (usually the hydrochloride form) in the pharmaceutical industry. There is relatively limited industrial exposure to this material.
| Chemical Properties | Pyrrolidine appears as a colorless to pale yellow liquid with an ammonia-like odor. It is infinitely miscible with water and conventional organic solvents such as methanol, acetone, ether, and chloroform. It acts as a lachrymator. Chemically, pyrrolidine behaves like a secondary amine in every respect. For example, it undergoes Leuckart –Wallach and Mannich reactions and is readily converted into an enamine. In the presence of a catalyst, such as platinum at 360°C or rhodium at 650°C, pyrrole is formed. In the presence of a copper catalyst, N-methylpyrrolidone is converted into N-methylpyrrolidine. |
| Application | Pyrrolidine is a heterocyclic compound used as a building block in the synthesis of wide range of pharmaceutical compounds, namely matrix metalloprotein inhibitors (MMPIs) and aminopeptidase N inhibitors (APNIs). It has been used for the synthesis of N-benzoyl pyrrolidine from benzaldehyde via oxidative amination. It may be used as a catalyst for the synthesis of N-sulfinyl aldimines from carbonyl compounds and sulfonamides. Pyrrolidine can also be used to synthesize: Taddol-pyrrolidine phosphoramidite, a ligand for rhodium-catalyzed [2+2+2] cycloaddition of pentenyl isocyanate and 4- ethynylanisole. H,4 PyrrolidineQuin-BAM (′PBAM′), a selective catalyst for the aza-Henry addition of nitroalkanes to aryl aldimines. 1,2,3,3a,4,9-Hexahydropyrrolo[2,1-b]quinazoline by reacting with o-aminobenzaldehyde. |
