Concise Synthesis of Complicated Polypropionates through One-Pot Dissymmetrical Two-Directional Chain Elongation

Pierre Vogel, Maris Turks, Claudia Jana Exner, Freddy Fonquerne

Herein, a major breakthrough in a sulfur dioxide-mediated oxyallylation cascade reaction is reported that allows the preparation of complex long-chain polyketide fragments with more than ten stereogenic centers through a carefully designed desymmetrization ...

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 ...

Dissymmetrical Double-Chain Elongation Approach to the Asymmetric Synthesis of Long-Chain Polypropionates

Claudia Jana Exner

Polyketides show interesting biological activities and therefore represent an important class of natural products. The necessity of their diastereo- and enantioselective synthesis led to the development of numerous methodologies. A brief overview of this t ...
