Abstract An expedient three‐step procedure for the synthesis of trichlorophenol derivatives based on the acid‐catalyzed rearrangement of the bicyclic ketone precursors 6a–e in high overall yield is described. The bicyclic ketone precursors 6a–e were obtained from Diels–Alder cycloadducts of β‐substituted vinyl acetates with tetrachloro‐5,5‐dimethoxycyclopentadiene in two steps.
摘要描述了基于双环酮前体 6a-e 的酸催化重排以高总产率合成三氯苯酚衍生物的便捷三步法。双环酮前体 6a-e 由 β 取代的乙酸乙烯酯与四氯-5,5-二甲氧基环戊二烯的 Diels-Alder 环加合物分两步获得。
