Ullmann Reaction for Vinyl Enol Ethers

Posted by naturalproductman on April 29, 2010

Craig Merlic and co-worker at UCLA have recently reported in Organic Letters on an Ullmann reaction from a vinyl boron substrate to couple to the oxygen of an allylic alcohol.  The yield was optimized in the presence of a terminal alkyne, which was used as a ligand for copper.
