Cerium-catalyzed α-oxidation of β-dicarbonyl compounds with molecular oxygen
β-Ketoesters and β-diketones are α-hydroxylated by molecular oxygen in the presence of 5 mol% CECl3-7 H2O in i-PrOH as solvent. The method is limited to substrates with an α-alkyl substituent. Optimal yields are achieved with cyclic

-Alkoxystannyl ethers in organic synthesis: Synthesis of functionalised γ-butyrolactones
Ozonolysis of a variety of (tetraydrofuran-2-yl)tri-n-butylstannanes affords the corresponding γ-butyrolactones in good to excellent yields. This reaction is tolerant to a range of other functional groups and provides access to substituted γ-butyrolactone
