The scope of the cycloaromatization of propargylic ethers was explored using operationally simple air- and moisture-insensitive conditions. Highly substituted phenol derivatives were obtained in high yields. Mechanistic experiments indicate that the reaction occurs by an electrocyclization followed by 1,3-proton transfer.
炔丙基醚的环化反应范围在操作简单、对空气和水分不敏感的条件下得到了探索。高取代基的苯酚衍生物以高产率得到。机理实验表明,该反应通过电环化反应然后进行 1,3-质子转移来发生。
