and six 20-O-acylated analogs were synthesized and tested for their antiproliferative activity. Both the C1-protecting group of the salinomycin and the acidity of the substituted benzoic acid are crucial to the Mitsunobu conversion. 20-epi-Salinomycin showed similar antiproliferative activity as salinomycin, but its 20-O-acylated analogs were 2–10 times more potent. In addition, the 20-epi-20-O-acylated
