Gold(I)-Catalyzed Tandem Cyclization–Selective Migration Reaction of 1,3-Dien-5-ynes: Regioselective Synthesis of Highly Substituted Benzenes info:eu-repo/semantics/acceptedVersion García García, Patricia Martínez Cuezva, Alberto Sanjuán Cortázar, Ana María Fernández Rodríguez, Manuel A. Sanz Díez, Roberto Química orgánica Chemistry, Organic Highly substituted benzene derivatives have been easily prepared in a regioselective way from readily available 1,3-hexadien-5-ynes through a gold(I)-catalyzed tandem reaction. The process involves an initial cyclization followed by a selective Wagner-Meerwein shift in which the migration preference seems to be determined by the ability to stabilize a positive charge Ministerio de Ciencia e Innovacion (MICINN) and FEDER (CTQ2010-15358 and CTQ2009-09949/BQU) and Junta de Castilla y Leon (BU021A09 and GR-172) for financial suport.
