合成路线1
该中间体在本合成路线中的序号：(IV)Ozonolysis of chloesteryl acetate (I) produced keto acid (II), which was converted to the B-homo-6-oxacholestenone (III) upon treatment with SOCl2. Subsequent displacement of the 3beta-acetate group of (III) by NaN3 afforded azide (IV). Pyrolysis of (IV) over silica gel at 180 C yielded a mixture of cleavage products, from which the title nitrile was isolated by column chromatography.

Subsequent displacement of the 3-beta-acetate group of (III) by NaN3 afforded azide (IV).
