Stereoselective preparation of highly functionalized (Z)-3-magnesiated enoates by an iodine-magnesium exchange reaction.
Sapountzis I., Dohle W., Knochel P.
3-Iodoenoates are converted into the corresponding alkenylmagnesium species with complete retention of configuration of the double bond; both direct reaction and copper(I)-mediated reactions with various electrophiles provide polyfunctional enoates.
