Article abstract of DOI:10.1016/S0040-4039(00)88138-1

Highly diastereoselective alkylations of propionates of chiral alcohols derived from (+)-camphor are described.It is demonstrated that steric shielding as well as cation complexation are important for stereoselection.The latter effects are in part rationa
