Abstract

The novel pyrimidine carboacyclonucleoside analogues containing propargylated aryl side chains were synthesized via palladium-catalyzed cross-coupling reactions as a key step. The synthesized compounds were screened for their antibacterial activity against four microorganisms: Staphylococcus aureus (CIP 53.154; Gram positive), Enterococcus hirae (CIP 58.55; Gram positive), Pseudomonas aeruginosa (CIP A22; Gram negative), Escherichia coli (CIP 54.8; Gram negative). Some of the prepared products showed promising antibacterial activity against the nosocomial E. hirae.
