title: Tetramethyl thiourea/Co2(CO)8-catalyzed Pauson-Khand reaction under balloon pressure of CO.
abstract: A Pauson-Khand type of conversion of enynes to bicyclic cyclopentenones employing the commercially available Co2(CO)8 and tetramethylthiourea (TMTU) as catalysts is described. This method allows a variety of enynes with diverse functional groups to be cyclized into cyclopentenones of interest. [reaction: see text]
