“…[12] Organocuprates are also known to undergo selective S N 2' addition with vinylepoxides. [13] Therefore, lithiated dithianes and organocuprates were chosen as the initiating nucleophiles (Figure 4 a). With lithiated TBSdithiane, the optimal reaction conditions include Et 2 O as the solvent, ambient reaction temperature, and a reaction time of two hours.…”

“…Bei diesem Syntheseansatz handelt es sich um die erste Thiolactomycinsynthese unter asymmetrischer Katalyse. Das tertiäre Sulfid wurde dann über eine S N 2'-Addition [188] von Thiopropionsäure in Gegenwart von Trimethylaluminium eingeführt, bei der die Addition syn zum Epoxid die Verbindung 285 ergab. Die Abspaltung der Silylgruppe und die vicinale Didesoxygenierung [189] des resultierenden Diols lieferten die Seitenkette von Thiolactomycin in der Verbindung 273, und die mittlerweile bekannte Dieckmann-Cyclisierung führte zum Naturstoff.…”

“…Having failed to prepare the alk-2-ene-1,4-diol moiety (6) from the diene derivatives of type 4 under the reported conditions, [7][8][9][10] we decided to study other alternatives. We envisaged that titanoceneA C H T U N G T R E N N U N G (III) chloride could be useful in the construction of the alk-2-ene-1,4-diol system from diepoxides derived from 1,3-dienes (Scheme 2).…”
