An α‐alkylation of the 2‐methylcycloalkanones 1 and 4 at the higher substituted carbon can be achieved by thioalkylation of the corresponding zinc enolates with the α‐chlorosulfides 3 . The desulfurization can be carried out with either Raney nickel or lithium in diethylamine for compounds which contain double or triple bonds.
