Abstract

We present an easy method for the synthesis of β-ketoesters starting from variouscarbocyclic and heterocyclic carboxylic acids and esters. The β-ketoester side-chain wasintroduced by a sequence involving α-deprotonation and quenching with CO2, conversion tothe corresponding acid chloride and subsequent chain elongation using deprotonated ethylacetate.
Keywords: Chain elongation; β-ketoesters; ethyl acetate; heterocyclic esters Chain elongation; β-ketoesters; ethyl acetate; heterocyclic esters
