Palladium-catalyzed oxidative difunctionalization of enol ethers with 1,3-dicarbonyl compounds to construct trisubstituted furans in one step under mild conditions is described. The reaction is thought to proceed through a C-C bond formation along with a C-O bond closing the ring

A one-pot two-step synthesis of versatile indenones has been developed. This palladium(II)-catalyzed transformation involves generation and condensation of ortho-functionalized 1,2-benzils from 2-(2-arylethynylphenyl)acetonitriles using Ph2SO as the oxidant. The resulting 3-cyanoindenones can be converted to various valuable molecules.

A novel Pd/Cu catalyzed domino reaction for the synthesis of functionalized pyrrolo[1,2-b]pyridazines from readily accessible (hetero)aryl propargyl alcohols and 1-amino-2-bromopyrroles was developed. This cascade process involves a Sonogashira cross-coupling reaction, an isomerization and an intramolecular condensation.

Racemic 4-hydroxycyclopentenone, readily derived from furfuryl alcohol, can be transformed via its O-Boc derivative to 4-acyloxy, 4-aryloxy-, 4-amino-, or 4-thio-substituted cyclopentenones with high enantioselectivity by palladium-catalyzed kinetic resolution via nucleophilic allylic substitutions. Applying this methodology, a short formal synthesis of
