The syntheses and the pregnancy-terminating activity relationships of compounds 5a-n are reported. Compounds 5b and 5l are found to be more potent than DL-111-a known drug having effective pregnancy-terminating activity in vitro. Further research shows compounds 5b and 5l have the same activity as DL-111 in vivo. We also found an exciting result that they have excellent anti-implantation activity after oral administration.
