合成路线1
该中间体在本合成路线中的序号：(IV)Synthesis of 5,6,6-trideuterated finasteride: The reaction of 3-oxo-4-aza-5-androstene-17beta-carboxylic acid (I) with D2O and CH3CO2D gives the monodeuterated compound (II), which, without isolation is hydrogenated with D2 over PtO2 to yield 5,6,6-(D)3-3-oxo-4-aza-5alpha-androstane-17beta-carboxylic acid (III). The dehydrogenation of (III) with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and bis(trimethylsilyl)trifluoroacetamide (BSTFA) affords 5,6,6-(D)3-3-oxo-4-aza-5alpha-androst-1-ene-17beta-carboxylic acid (IV), which is esterified with 2,2'-dithiopyridine (V) and triphenylphosphine in toluene to give the corresponding thioester (VI). Finally, this compound is treated with tert-butylamine (VII) in THF).
