Novel homologated 19-oxiranyl- and 9-thiiranylandrost-4-ene-3,17-diones (8a,b and 9a,b, respectively) have been synthesized. The configuration and conformation of compound 8a have been established by X-ray crystallographic analysis. All four compounds have been shown to be competitive inhibitors of human placental aromatase. The thiiranes were more potent inhibitors than the corresponding oxiranes
