合成路线1
该中间体在本合成路线中的序号：(II)Treatment of dehydroepiandrosterone 3-acetate (I) with triflic anhydride and 2,6-di-tert-butyl-4-methylpyridine provided the desired enol triflate (III) along with some 3,5-diene (II), which were separated by column chromatography. Subsequent coupling of triflate (III) with pyridylborane (IV) using bis(triphenylphosphine)- palladium(II) chloride as the catalyst afforded the (3-pyridyl)androstadiene (V), which after hydrolysis of the acetate ester with NaOH provided the target compound.
