The oxidative cyclisation of 3-(1-hydroxyethyl)-,1,4-dimethoxy-2-prop-1-enylnaphthalene with four equivalents of ceric ammonium nitrate to afford two 4-hydroxy-1,3-dimethylnaphtho[2,3-c]pyran-5,10-quinones with the same stereochemistry as quinones A and A′, derivatives of the aphid pigments protoaphin-fb and protoaphin-sl, is described. Certain aspects of the mechanism have been established.
3-(1-羟乙基)-,1,4-二甲氧基-2-丙-1-烯萘与四当量硝酸铈铵的氧化环化反应,得到两个4-羟基-1,3-二甲基萘[2,3-描述了具有与醌A和A'相同的立体化学的c ] pyran-5,10-醌,这是蚜虫色素protoaphin- fb和protoaphin- sl的衍生物。该机制的某些方面已经建立。
