A mild Pd-catalyzed addition of indoles to hydroxy 1,6-enynes has been developed. In this reaction, hydroxy 1,6-enynes were selectively transformed into (E)-3-styryl-2,5-dihydro-1H-pyrrole derivatives.

regioselective intermolecular Alder‐ene‐type reaction of alkynes with 1,2‐disubstituted alkenes. The increased substrate scope opens new perspectives in stereochemical terms. As the loaded catalyst is chiral‐at‐metal, stereochemical information is efficiently relayed from the propargylic site to the emerging C−C bond. This interpretation is based on the X‐ray structure of the first Cp*Ru complex carrying
