  • Title: Au(I)-catalyzed intramolecular oxidative cyclopropanation of 1,6-enynes derived from propiolamides with diphenyl sulfoxide.
    Author: Yeom HS, Shin S.
    Journal: Org Biomol Chem; 2013 Feb 21; 11(7):1089-92. PubMed ID: 23321793.
    Abstract:
    We have developed gold(I)-catalyzed oxidative cyclopropanation of 1,6-enynes derived from propiolamides employing diphenyl sulfoxide as an oxidant. 1,6-Enynes having a terminal alkyne and a propiolamide tether efficiently transformed into cyclopropane carboxaldehyde derivatives.
