Francis Barabé et al.
Organic letters, 13(20), 5580-5583 (2011-09-16)
A gold-catalyzed synthesis of fused carbocycles via a regioselective 6-endo dig process is reported. The selectivity can be modulated by the steric and electronic properties of gold(I) complexes. The ligands can influence the pathway selectivity for the first bond formation
