Gold-Catalyzed Synthesis of Bicyclo[4.3.0]nonadiene Derivatives via Tandem 6-endo-dig/Nazarov Cyclization of 1,6-Allenynes

Catalytic cyclization of 1,6-allenynes was achieved by AuPPh3SbF6 (5 mol %) in cold CH2Cl2 (0 °C, 0.5−4 h) to form bicyclo[4.3.0]nonadiene products; this cyclization proceeded more efficiently for a substrate bearing R = alkyl (yields >70%). We propose a reaction mechanism involving a 6-endo-dig...
