Abstract:A series of heterocyclic analogs of diarylethylene and triarylethylene were synthesized as potential anti‐implantation agents. Tested in rats as oral, post‐coital antifertilily agents, a few of our compounds showed some activity.
Electron impact mass spectra of eight of the title compounds are discussed. Based on our data a mechanism for the formation of the m/e 91 ion is proposed. Fragmentation pathways have been confirmed by measurement of the metastable peaks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
