Description

Product Detail

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.

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.
