Synthesis and Antibacterial Properties of β-Diketone Acrylate Bioisosteres of Pseudomonic Acid A. -Fourteen bioisosteres like (V) and (IX) are synthesized and evaluated for their antibacterial activities. The first synthesis of the diketone system (V) uses a base-catalyzed deconjugation process. The second synthesis of system (IX) is complementary to that of system (V) and the ready availability of aldehydes (VII) makes this synthesis the preferred sequence. Optimal activity is observed with small para-phenyl…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
