Abstract
The gold (I)-catalyzed endo-cyclization of o-(1-hydroxyallyl) phenols to form chromenes is reported. The title compounds are prepared in high yield from readily available substrates. The system tolerates both electron rich and deficient aryl rings and a high degree of substitution on the allyl moiety.
