Synthesis of Novel Sterically Demanding Carbo- and Heterocyclic β-Ketoesters
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.
