Gabapentin, an anticonvulsant used in the treatment of epilepsy, is structurally related to the neurotransmitter 4-aminobutanoic acid (GABA). -NH2 -NH, B -СООН COOH Gabapentin 4-Aminobutanoic acid (y-Aminobutyric acid, GABA) Gabapentin was designed specifically to be more lipophilic than GABA and therefore more likely to cross the blood-brain barrier, the lipidlike protective membrane that sur- rounds the capillary system in the brain and prevents hydrophilic (water-loving) com- pounds from entering the brain by passive diffusion. Given the following retrosynthetic analysis, propose a synthesis for gabapentin. -NH, -NH2 CN COOH -COOEt COOEt Gabapentin COOEt COOE. O + COOEt COOEt Cyclohexanone Diethyl malonate

Why is retrosynthesis seen as a very important approach in the synthesis of organic compounds, explain the steps in retrosynthesis and apply them in the synthesis of p-amino benzoate analgesics. Why is a protective group needed in the synthesis stage ?
