title: Contraceptive agents from cycloaddition reactions of diarylcyclopropenones and diarylthiirene 1, 1-dioxides.
abstract: The potential for compounds with antifertility activity from the reactions of diphenylcyclopropernone (1) and 2, 3-diphenylthiirene 1, 1-dioxide (2) with enamines is described. In certain instances, a marked dissociation of antifertility from estrogenic activity was possible. Two series were studied extensively, one was stilbene amides (7) and the other stilbene amino ketones (8). The latter series (8) afforded several materials from which, on further biological work-up, was singled out compound 21 as a potent antifertility agent in rats and hamsters.
