Synthesis of 9-Substituted Xanthenes by the Condensation of Arynes with ortho-Hydroxychalcones
The reaction of o-(trimethylsilyl)aryl triflates, CsF, and o-hydroxychalcones affords a general and efficient way to prepare biologically interesting 9-substituted xanthenes. This chemistry presumably proceeds by tandem intermolecular nucleophilic attack of the phenoxide of the chalcone on the aryne...
