Ethyl 4-(2-(1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)ethoxy)-3-oxobutanoate

Synthesis of amlodipine-related compounds and other dihydropyridine derivatives. It serves as a protected β-ketoester building block in multistep organic synthesis. Ethyl 4-(2-(1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)ethoxy)-3-oxobutanoate (CAS 88150-75-8) is used mainly as a synthetic intermediate in pharmaceutical and organic chemical synthesis rather than as an active drug itself.
