A general method of synthesis of functionalized Z-vinylic tellurides starting from β-dicarbonyl compounds

Add time:08/25/2019 Source:sciencedirect.com
Z-Vinylic tellurides are prepared by stereoselective vinylic substitution on Z/E mixtures of enolphosphates, acetates, tosylates and triflates by organotellurolates. The reaction is sensitive to the nature of the organotellurolate; the aromatic derivatives react slower than the aliphatic ones. The reaction time is not influenced by the nature of the leaving group.
