Synthesis and Biological Evaluation of Functionalized Epoxides Structurally Related To the Carbapenem Family
Epoxides (6) and (7), topologically related to the carbapenem antibiotics, were designed as potential alkylating inhibitors of the bacterial D,D-peptidases. The olefinic precursors (8-9) were readily prepared, in three steps, by coupling the Wittig reagent (13) with the aldehyde synthons (10) or (11) resulting from diastereoselective aldol condensations. Epoxide (7) showed a weak anti-beta-lactamase activity.
