benzannulated enediynyl alcohols with trifluoroacetic acid at room temperature promoted a cascade sequence of cyclization reactions, leading to 1,4-naphthoquinone methides. The transformation involved an unusual two-carbon ring expansion from the cyclic alcohols and the construction of the p-quinone methide ring from an acyclic system along the reaction pathway.
在室温下用三氟乙酸处理苯并二烯化炔醇可以促进环化反应的级联序列,从而生成1,4-萘醌甲基化物。该转化涉及从环醇中不寻常的二碳环膨胀和沿着反应路径从无环系统构建对苯二甲酰甲基环。
