Treatment of several 4a-acyl-4a,5,8,8a-tetra-hydro-1,4-naph thoquinones with boiling acetic anhydride gives the 1,4-diacetoxy-2-acyl-5,8-dihydronaphthalenes, and the corresponding 1,4-dihydroxy-compounds are formed when acetic acid is used, but the latter are more readily obtained, via the Δ8a,1enols, by treatment with pyridine or pyridine–methanol, these basic reagents cause deformylation of the 4a-formyl
用沸腾的乙酸酐处理几种4a-酰基-4a,5,8,8a-四氢-1,4-萘醌,可得到1,4-二乙酰氧基-2-酰基-5,8-二氢萘,以及相应的当使用乙酸形成1,4-二羟基化合物,但后者更容易获得,经由所述Δ 8a中,1个烯醇,通过与吡啶或吡啶-甲醇处理,这些碱性试剂原因4A甲酰基的脱甲酰咪唑类似的化合物,但在C-4处的正构基团转移到氧上可以用咪唑完成。
