[Image: see text] The first Pd(0)-catalyzed Nazarov-type cyclization of diketoesters proceeds in 70% to 95% yield under strictly neutral conditions. Aryl substitution is not required so the reaction succeeds with aliphatic substrates. The mechanism appears to be novel. A single asymmetric version of this reaction is also reported.
