INTRAMOLECULAR PAUSON-KHAND REACTIONS OF AROMATIC ENYNES

Abstract

Abstract The synthesis of a series of O-alkenylated ethynylphenol derivatives and their NMO promoted intramolecular Pauson-Khand reactions are reported. The effects of substitution on both the alkene and alkyne moiety have been investigated. ACKNOWLEDGMENTS We would like to thank The University of Texas at Arlington (Start-up Funds) and the Robert A. Welch Foundation for the provision of financial support for this project.
