Article abstract of DOI:10.1039/c39910000391

The stereoselectivity of the Lewis acid induced acylation of open-chain silyl enol ethers by chiral orthoesters is strongly affected by the C=C bond configuration: both Z and E silyl enol ethers are acylated in good isolated yields, but the Z isomers give
