“…25 In 2009, Kim's group developed a direct and efficient approach to access 5-hydroxybenzofurans 47 under platinum catalysis (Scheme 18). 26 Enynols 46 bearing both aryl and alkyl groups were compatible with this protocol, and a series of 5-hydroxybenzofurans 47 were successfully formed in moderate to excellent yields under mild conditions. This novel transformation proceeded via a platinum-catalyzed cascade dienone-phenol rearrangement/5endo-dig cyclization sequence to afford the target products.…”
