dehydrogenation reaction applied to 19-norsteroids 1a or 1b, with copper(II) bromide in different alcohols yielded estrone alkyl ethers or 13β-ethyl-3-alkoxy gonanes along with products in which the steroid 6-position has been oxidized as well. Use of small amounts of trialkyl orthoformates in the reaction considerably diminished the overoxidized products.
