Oxidative Decarboxylation as a Route to Ketene Acetals: Assignment of Relative and Absolute Stereochemistry to the Fungal Metabolite Benesudon by Total Synthesis. -The synthetic studies reveal that the relative configuration assigned to the title compound must be revised at C-5 and that the absolute configuration of the natural product is represented by structure (I). -(CLIVE*, D. L. J.; MINARUZZAMAN; Org. Lett. 9 (2007) 25, 5315-5317; Dep. Chem., Univ. Alberta, Edmonton, Alberta T6G 2G2, Can.; Eng.) -Lindner 19-220

2005 Furan derivatives R 0060 Conversion of Furans into γ-Hydroxybutenolides: Use of Sodium Chlorite. -Treatment of 3,4-disubstituted furans with NaClO2/NaH2PO4 offers a general and effective approach to γ-hydroxybutenolides. However, ester-substituted furans do not undergo transformation. -(CLIVE*, D. L. J.; MINARUZZAMAN; OU, L.; J. Org. Chem. 70 (2005) 8, 3318-3320; Dep. Chem., Univ.
