Reductive alkylation of various 4-cyano-2-cyclohexenones, readily available from α-cyano ketones via a Robinson annulation process, gave rise to the corresponding 2,2-disubstituted-3-cyclohexenone derivatives in a completely regioselective manner. Application of this methodology resulted in an efficient synthesis of the marine natural product nanaimoal in racemic form.
