α-hydroxy cyclopentenones from α-diketones

(Chemical Equation Presented) Metalloenolates derived from α,β-unsaturated α-diketones undergo cyclization to α-hydroxy cyclopentenones. This is apparently the first reported Nazarov reaction that takes place in the presence of base.

The Palladium(II)-Catalyzed Nazarov Reaction

(Equation presented) The PdCl2-catalyzed cyclization of α-alkoxy dienones leads to 2-hydroxycyclopentenones, whereas the Pd(OAc)2-catalyzed reaction leads to cross-conjugated cyclopentenones through an oxidative process.
