What is malonic ester formula?

Malonic ester synthesis is a synthetic procedure used to convert a compound that has the general structural formula 1 into a carboxylic acid that has the general structural formula 2. R1 = alkyl group. L = leaving group.

Why malonic ester is important?

It is used to prepare alkylated derivatives of acetic acid and other carboxylic acids rather than derivatives of acetone or other ketones prepared by the acetoacetic ester synthesis. The a hydrogen atom of diethyl malonate is sufficiently acidic to be deprotonated by ethoxide ion.
