δ-Alkenyl oximes of 13α-estrone 3-methyl ether undergo intramolecular 1,3-dipolar cycloaddition reactions with BF3•OEt2 as catalyst, furnishing isoxazolidines. The reactions of the 13α- and 13β-estrone oximes with electrophiles lead to cyclic n

The naturally occurring steroid dehydroepiandrosterone (DHEA) is reported to reduce glial fibrillary acidic protein (GFAP) overexpression in a model of reactive gliosis due to its conversion to estradiol by the enzyme aromatase. In the present study
