Alkylations. Alkylation at the a-carbon of ethyl acetoacetate via an alkali metal enolate and subsequent removal of the ester group by sequential hydrolysis and decarboxylation provides a classical synthesis of methyl ketones (eq 1). 8 The ambident reactivity of the acetoacetate anion often causes competing C- and O-alkylations. 9 The extent of C vs. O alkylation depends on the nature of the.
