1,6-Diynes with a t-butylcarbonate group in the propargylic position undergo gold(I)-catalyzed domino-cyclization which affords α-hydroxycyclohexenones. The described sequence can be applied on functionalized, highly oxygenated substrates, as examplified in the synthesis of (-)-gabosine H and its epimer.
