Abstract

The E/Z-selectivity in the formation of silylketene acetals derived from phenylacetate esters, mediated by LiHMDS, has been studied by in situ NMR techniques. The formation is seen to be highly E-selective with use of the newly developed protocol. Isolated aryl-substituted silylketene acetals are now attainable with high levels of E-geometrical purity in excellent yield.
