Diastereoselectivity of the reactions of organolithium reagents with protected erythrulose oximes

The addition of organolithium reagents to the C=N bond of several erythrulose-derived chiral (E)- and (Z)-ketoxime ethers has been shown to be highly diastereoselective in the case of the (E)-isomers. Chelated and nonchelated transition states have been proposed to rationalize these results, with additional support of computational methods.
