Lewis acid/CpRu dual catalysis in the enantioselective decarboxylative allylation of ketone enolates. | LitMetric

Lewis acid/CpRu dual catalysis in the enantioselective decarboxylative allylation of ketone enolates.

Org Biomol Chem

Département de Chimie Organique, Université de Genève, Quai Ernest Ansermet 30, 1211 Genève 4, Switzerland.

Published: October 2009

The addition of a Lewis acidic metal triflate salt Mg(OTf)(2) as co-catalyst in the CpRu-catalyzed decarboxylative allylation of in situ-generated ketone enolates allows the reaction to proceed at lower temperature with higher regio- and enantioselectivity. Even so-far-unreactive substrates react.
