Regiospecific syntheses of 6alpha-(1R-Hydroxyoctyl)penicillanic acid and 6beta-(1R-hydroxyoctyl)penicillanic acid as mechanistic probes of class D beta-lactamases

Org Lett. 2009 Jun 18;11(12):2515-8. doi: 10.1021/ol900668k.

Abstract

The unique hydrophobic surface patches in class D beta-lactamases presented an opportunity for designing two compounds, 6alpha-(1R-hydroxyoctyl)penicillanic acid and 6beta-(1R-hydroxyoctyl)penicillanic acid, 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.
