6,6-Bis(phenylselenyl)penicillanate 2a was converted into 6-1'-(R)-hydroxyethyl substituted penicillanate 5 in high yield.Compound 5 was deselenylated to 10.Oxidation, and then the basic epimerization of cis sulfone 11 gave trans sulfone derivative 12.The trans sulfone 12 was degraded to the monocyclic β-lactams 14, 15 which are important precursors for the carbapenem synthesis.
