Abstract

(E)-Arylaldehyde oxime ethers bearing a (1 S)-2-hydroxy-1-phenylethyl or (2 R)-1-hydroxy-2- phenylethyl group as a chiral auxiliary, both derived from a single precursor, methyl (R)- mandelate, underwent nucleophilic addition with organolithium reagents via six-membered chelates to give the diastereomerically enriched (R)-and (S)-adducts, respectively, which, after chiral auxiliary removal by reductive NO bond cleavage, led to the corresponding (R) ...
