Nickel-catalyzed enantioselective cross-couplings between symmetric cyclic sulfates and aromatic Grignard reagents are described. These reactions are effective with a broad range of substituted cyclic sulfates and deliver products with asymmetric tertiary carbon centers. Mechanistic experiments point to a stereoinvertive SN2-like oxidative addition of a nickel complex to the electrophilic substrate.

This invention relates to a new method for the preparation of amines containing alkylene groups by using cyclic alkylene sulphuric esters, and novel intermediates for use in the method. The new method is useful for preparation of i.a. pharmaceuticals. The novel intermediates are useful i.a. as surfactants.
