Synthesis and Applications of Silyl 2-Methylprop-2-ene-1-sulfinates in Preparative Silylation and GC-Derivatization Reactions of Polyols and Carbohydrates

Pierre Vogel, Dean Markovic, Maris Turks, Sylvain Claude Laclef

Trimethylsilyl, triethylsilyl, tert-butyldimethylsilyl, and triisopropylsilyl 2-methylprop-2-ene-1-sulfinates were prepared through (CuOTf)(2)C6H6-catalyzed sila-ene reactions of the corresponding methallylsilanes with SO2 at 50 degrees C. Sterically hinde ...

Total Asymmetric Syntheses of beta-Hydroxy-delta-lactones via Umpolung with Sulfur Dioxide

Pierre Vogel, Maris Turks, Sylvain Claude Laclef, Claudia Jana Exner, Florent Poli

Cyclic stereotriads and stereotetrads of the beta-hydroxy-delta-lactone type, e.g. prelactones B and E, common in polyketides and polypropionates, are prepared via SO2-induced oxyallylations of enoxysilanes with (1E,3Z)-1-(1-phenylethoxy)penta-1,3-dien-3-y ...

Total Synthesis of Dolabriferol and Polypropionate Fragments Applying New Organic Chemistry of Sulfur Dioxide

Sylvain Claude Laclef

Polypropionates are common products of metabolism in bacteria, insects, fungi and marine organisms. They constitute an important class of products with a wide range of interesting biological activities. Our group has shown previously that 1-alkoxy-3-acylox ...
