The diastereotopic chemical shift differences of the H-1 and C-13 NMR signals of the adducts formed by addition of (N-methylphenylsulfoximidoyl)methyllithium (2) to cyclic ketones has been studied. The stereodifferentiation of the proton and carbon atoms follow a very regular pattern and the rule that can be drawn provides an alternative and complementary method to earlier procedures for the determination of absolute configuration of six-membered ring ketones.
