Lithium ester enolates, prepared by the reaction of lithium N-isopropylcyclohexylamide (LIICA) with esters at -78' (eq. 1); react with acid chlorides at this same low temperature to provide satisfactory yields of the corresponding S-keto esters (eq. II). This procedure represents an exceedingly vers
