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

For the enantio- und diastereoselective synthesis of the prodrug 2, the N-tert-butyloxycarbonyl-protected amine 7 was alkylated with the enantiopure epoxide 14 to give the amide 10. A regio- and facial-selective metal-mediated cyclisation by using a

Epoxidation of barrelene (3) with a neutralized solution of Oxone® gave the barrelene trisepoxide 6 in 82 % isolated yield, while lead tetraacetate promoted aziridination of 3 with two equiv. of N-aminophthalimide gave a mixture of mono-7 and bis(az
