    摘要: Methods are provided for synthesis of abscisic acid and 8′ analogues thereof (including an enantiopure 8′-acetylene analogue) including methods wherein the previously reported first step of oxidation of 2,6-dimethylphenol (VI) to 2,6-dimethylbenzoquinone, mono ketal (VII) is replaced by a novel two step process comprising (i) oxidation of 2,6-dimethylphenol (VI) using potassium peroxymonosulfate with a catalytic amount of iodobenzene to produce 2,6-dimethylbenzoquinone (XVI) and (ii) ketalization of 2,6-dimethylbenzoquinone (XVI) using ethylene glycol, trimethylorthoformate with a catalytic amount of p-toluenesulfonic acid to produce 2,6-dimethylbenzoquinone, mono ketal (VII).

    摘要: A method is described for the simultaneous preparation of p-bromophenols and p-benzoquinones, intermediates useful in the preparation of hydroquinones and 4,4null-dihydroxybiphenyls, respectively. Hydroquinones and 4,4null-dihydroxybiphenyls are useful monomers for the preparation of a variety of polymers. The method also comprises reducing the p-benzoquinone to its corresponding hydroquinone in the presence of the p-bromophenol. Limiting the amount of HBr present in the reaction mixture was shown to control the amount of benzoquinone produced. The method also allows for the recycling of many of the reagents used, thereby reducing the cost of producing each monomer.
