propargylic alcohols prepared from the catalyticasymmetric enyne addition to aliphatic aldehydes are used to prepare a series of opticallyactive trienynes. In the presence of a catalytic amount of [RhCl(CO)2]2 and 1 atm of CO, the opticallyactive trienynes undergo highly stereoselective domino Pauson–Khand/[4 + 2] cycloaddition to generate opticallyactive multicyclic products. The Rh(I) catalyst
