NaHSO/SiO catalyzed generation of -quinone/ -thioquinone methides: synthesis of arylxanthenes/ arylthioxanthenes oxa-6π-electrocyclization

ortho -Quinone methides, very reactive transient intermediates, are utilized successfully in synthesizing complex organic molecules of natural and biological significance. Among several synthetic protocols, the acid catalyzed generation of ortho -quinone methides from suitably substituted phenols is...
