A similar ring-opening reaction leading to homoallylic amine derivatives has been observed recently by Carreira and co-workers in the Co- or Mn-catalyzed radical hydrohydrazination of vinylcyclopropanes. However, there is no experimental evidence that the Au-catalyzed reaction takes place via radical intermediates; see: J. Waser, B. Gaspar, H. Nambu, E. M. Carreira, J. Am. Chem. Soc. 2006, 128, 11693
