Significance
A novel mode of reactivity in metal-catalyzed cycloisomerization of propargylic esters is described. The crucial result shown in this report is the ability of a copper catalyst, which is rarely used in these types of reaction, to yield rearranged products smoothly. This is one of the first examples where alkoxyalkyne substrates were used.
