title: [Unexpected formation of an estrone derivative from androsta-1,4-diene-3,17-dione].
abstract: Reaction of androsta-1,4-diene-3,17-dione (1) with pyrrolidine and p-toluenesulfonic acid in toluene gives 3-pyrrolidino-estra-1,3,5(10)-triene-6,17-dione (7) in poor yield, whose structure is shown by X-ray analysis. Compared with 3H-estradiol, compound 7 shows only a weak receptor binding activity tested in an in vitro screening using rabbit uterus cytosol.
