Now even unstrained alkenes can be used in catalytic intermolecular Pauson-Khand reactions [Eq. (a)]. This is made possible by the use of the directing group dimethyl(2-pyridyl)silyl, which can be easily removed at the end of the reaction. Furthermore, one observes completely regioselective incorporation of substituents at the 4- and 5-positions of the 2-cyclopentenone structure.
