heteroatom, react with Grignardreagents with high levels of regio- and stereochemical control. The substrates can be prepared in the optically pure form by the Zr-catalyzed kinetic resolution; subsequent reaction with alkylmagnesium halides leads to the formation of optically pure alkylation products. The studies outlined herein probe the influence of the length and position of the heteroatom side
