Product Description

It is a key chiral phosphonium intermediate widely used in the synthesis of carbapenem and penem antibiotics, serving as a critical building block for constructing the bicyclic β-lactam core structure.
This compound features a rigid bipyrrolidine skeleton with defined (R)-configuration at the 3'-position, enabling highly stereoselective Wittig coupling reactions. It ensures high chiral purity and efficient formation of the characteristic exocyclic double bond in the final antibiotic molecule.

Key Features

  • High chiral purity (3'R)
  • White to off-white crystalline powder
  • Strict stereochemical control
  • Stable under low-temperature, dry conditions
  • Optimized for industrial API synthesis
