The unique hydrophobic surface patches in class D β-lactamases presented an opportunity for designing two compounds, 6α-(1R-hydroxyoctyl)penicillanicacid and 6β-(1R-hydroxyoctyl)penicillanicacid, as mechanistic probes of these enzymes. In a sequence of three synthetic steps from benzhydryl 6,6-dibromopenicillanate, the targeted compounds were prepared in a stereospecific manner.
