Another Nazarov? Or not.
Posted by naturalproductman on August 31, 2012
Zhang-Jie Shi and co-workers at Peking University have reported in Organic Letters on a palladium catalyzed cyclization process, which at first glance looked like it may be a Nazarov reaction but they proved that it probably is not a Nazarov reaction because of the observed kinetic isotope effect when they replaced the aryl hydrogens with deuteriums.
