The PCC/SiO2-promoted double oxidation of 3-cyclohexene-1,2-diols, which were easily prepared by the two-step sequence of α′-hydroxylation of various conjugated cyclohexenones and the subsequent nucleophilic carbonyl addition of alkyl anions, produced diversely substituted 1,4-hydrobenzoquinones.
PCC/SiO2催化的3-环己烯-1,2-二醇的双重氧化反应,经过两步反应序列轻松制备而成:首先是对各种共轭环己烯酮的α'-羟基化,随后是烷基阴离子的亲核碳基添加反应,最终生成了多种取代的1,4-氢苯醌。
