Table 1. Intramolecular Pd-Catalyzed Alkene Carboamination Reactionsa.
Conditions: 1.0 equiv of substrate, 2.0 equiv of NaOtBu, 2 mol % Pd2(dba)3, 8 mol % PCy3·HBF4, toluene (0.1 M), 105 °C.
Isolated yields (average of two or more experiments).
This compound contained ca. 25% of an inseparable impurity tentatively assigned as 6-methyl-11-methylene-5,6,11,12-tetrahydrodibenzo[b,f]azocine, which results from competing intramolecular Heck arylation of the substrate.
