Abstract

In a modification of the Wierenga-Skulnick β-ketoester synthesis, the dianions of malonic acid mono-amides were condensed with acid chlorides. Acidic workup led to decarboxylation and isolation of the corresponding β-keto amides in good-to-excellent yields. A similar procedure with cyanoacetic acid gave β-keto nitriles.

Key words

amides - carboxylic acids - condensation - ketones - nitriles
