Total synthesis of (-)-2-methoxy-2-butenolide-3-cinnamate and its antimicrobial potentials

Abstract

The first total synthesis of (-)-2-methoxy-2-butenolide-3-cinnamate (butenolide cinnamate) was achieved using commercially available starting material. The synthesized compound was found to have promising antibacterial activity against Gram-negative strains Escherichia coli (ATCC 8739), Salmonella typhimurium (ATCC 23564) and Pseudomonas aeruginosa (ATCC 19154) with a minimum inhibitory concentration of 2.0 µg/mL, 1.0 µg/mL and 2.0 µg/mL, respectively. Notably, the compound was more potent against Gram-negative test strains than the Gram-positive test strains.
