摘要：Esters of 3-oxocarboxylic acids are prepared by acylation of the magnesiumenolates of acetoacetates with carboxylic acid chlorides and elimination of the acetylgroup from the acylacetoacetates formed as intermediate. Yields and purity of theproducts are considerably improved by addition of a tertiary amine during the acylation.
