Regioselective α-Alkylation of Silyl Enolates using a Mild Catalyst- ZnCl2 Doped on Acidic Alumina
ZnCl 2 doped acidic alumina used as a solid support acts as a better Lewis acid in the SNl reaction of trimethyl silyl enol ethers with 3 0 , allylic and benzylic halides to yield exclusively the substituted product in excellent yields. This method has been employed for the synthesis of monocyclic s...
