Title: A highly adaptable catalyst/substrate system for the synthesis of substituted chromenes. Author: Aponick A, Biannic B, Jong MR. Journal: Chem Commun (Camb); 2010 Sep 28; 46(36):6849-51. PubMed ID: 20730147. 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.[Abstract] [Full Text] [Related] [New Search]
