合成路线1
该中间体在本合成路线中的序号：(V)2) By the reaction of 3-oxoandrost-4-ene-17beta-carboxylic acid (III) with diisopropylcarbodiimide (II) in refluxing ethyl acetate and subsequent A-ring opening of compound (IV) by treatment with the Lamieux-von Rudloff reagent (permanganate-periodate) in isopropanol. The cyclization of the secoacid (V) so obtained, with methylamine in dioxane under pressure, followed by the hydrogenation under pressure, on 10% Pd/C in ethanol, affords turosteride. This method is used for the large scale production of turosteride.
