该中间体在本合成路线中的序号：(II)The esterification of 5,8-dihydro-1-naphthol (I) with acetic anhydride gives the corresponding acetate (II), which is oxidized with silver acetate and I2 in acetic acid to yield 2,3-cis-1,2,3,4-tetrahydro-2,3,5-naphthalenetriol (III). The treatment of this product with sodium methylate and epichlorhydrin (A) in methanol gives 2,3-cis-1,2,3,4-tetrahydro-5-(2,3-epoxypropoxy)-2,3-naphthalenediol (IV), which is finally treated with tertbutylamine (B) in chloroform-methanol.
