Recently we developed an efficient proceedure to alkylate B-keto esters at the Y carbon. 1 This involved treating the starting 8-keto ester with one equivalent of sodium hydride, then with one equivalent of n-butyllithium to give the dianion &, and finally alkylation at the more nucleophilic termin
