Chiral Synthesis of the Key Intermediate for 1β-Methylcarbapenem Antibiotics Starting from (-)-Carvone

A stereoselective synthesis of the key intermediate for the preparation of 1β-methylcarbapenem antibiotics was achieved by using a cyclopentanone derivative, easily derived from (-)-carvone, as a starting material.
