A Direct Approach to 5-Hydroxybenzofurans via a Platinum-Catalyzed Domino Rearrangement/5-endo-dig Cyclization Reaction of Quinols
摘要:
A highly efficient and atom-economical construction of 2-substituted 5-hydroxybenzofurans was accomplished by employing a platinum-catalyzed domino dienone-phenol rearrangement/5-endo-dig cyclization reaction of quinols bearing alkynes.
