A highly adaptable catalyst/substrate system for the synthesis of substituted chromenes
2010
Aponick, Aaron | Biannic, Berenger | Jong, Michael R.
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.
