Palladium (II) Mediated Transformation: Exploring Synthetic Methodology for the Synthesis of Cyclopentenones from Tertiary-Cyclobutanois
… ring-fused cyclopentanone followed by Saegusa-Ito reaction to furnish final cyclopentenone product. Extensive efforts to transform this reaction into a catalytic process by screening various palladium(II) sources, ligands, oxidants, bases, solvents and reaction temperatures failed. …

Studies toward a total synthesis of (±)-subergorgic acid
… 98 via a four step sequence, involving Saegusa oxidation to give 156, deketalization of the ketal function and benzeneseleninic acid anhydride (BSA) mediated dehydrogenation of the intermediate 157. The dienedione 98 was alkylated to provide 107. Conversion of the enone 157 into the …

I. Progress Toward Leiodelide A II. Palladium-Catalyzed Reactions of Enol Ethers
… far lower than those used in traditional Saegusa oxidations of silyl enol ethers. Despite a number of published modifications of the Saegusa oxidation allowing for lower loadings of palladium, a full equivalent of palladium is still often used in the synthesis of natural products. The …

New Methods for Palladium-catalyzed Decarboxylative Benzylation, Arylation and Dearomatization Reactions
… and basic reagents. Since the initial reports by Saegusa and Tsuji on decarboxylative allylation (DcA) of β-ketoesters in 1980, this concept remained relatively unexplored until the independent reports from Tunge and Stoltz in 2004. Since then, couplings of a broad array of nucleophiles, as well …
