  Formation of Carbon-Carbon Bonds via Quinone Methide-Initiated Cyclization Reactions

  摘要：

  p-Quinone methides were found to be excellent electrophilic cyclization initiators for the formation of six-membered rings. Cyclizations to form five- and seven-membered rings were also studied. Oxidation of 2,6-disubstituted phenols with Ag2O afforded the corresponding quinone methides. A wide range of cyclization terminators/nucleophiles were found to be effective in the cyclizations, including: allylsilane, beta-keto esters, furan, pyrrole, indole, and a number of alkenes. The yields of the cyclizations were generally high.
