Silylene protection of two dihydroxy groups of the peri-hydroxy aromatic sulfides 6a-f was essential for the subsequent Pummerer-type reaction. The overall process provided a novel and efficient approach to the peri-hydroxy dihydroquinone derivatives 9a-f.
邻羟基芳族硫化物6a-f的两个二羟基的亚甲硅烷基保护对于随后的Pummerer型反应是必不可少的。整个工艺提供了一种新颖和有效的方法来迫羟基二氢醌衍生物9A-F 。
