Descripción

General description

Pyrrolidine is a heterocyclic building block used in organic synthesis and a scaffold for biologically active compounds.

Application

Pyrrolidine 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.{88]
• 1,2,3,3a,4,9-Hexahydropyrrolo[2,1-b]quinazoline by reacting with o-aminobenzaldehyde.
