The au(I) catalyzed activation of allenamides and their subsequent transformation into chromanes: a method for the regiocontrolled addition to the alpha- and gamma-positions of the... by Natasha H. Slater, Natalie J. Brown, Mark Elsegood, Marc Kimber

“…Au(I) activation of allenamides in the presence of phenols leads to the formation of chromanes in moderate to good yields. This catalytic process is dependent on the counterion which facilitates the activation of the in situ formed imine. …”
