Abstract

Pauson-Khand reactions are carried out with different substituted aromatic enynes yielding tricyclic cyclopentenones related to natural products. Reaction is promoted by dissolved Me3NO. Isomerization of the double bond of the cyclopentenone is observed except for compound 2e, with a non terminal triple bond.
