Description General description Dimethyl acetylsuccinate undergoes sulfuric acid catalyzed Pechmann condensation with the corresponding resorcinol derivative to give 7-hydroxycoumarins. Application Dimethyl acetylsuccinate has been used in the synthesis of 2-oxofuro[2,3-b]pyrroles and 19-methyl-15-oxa-20-azatricyclo[12.3.3.0(1,14)]icos-18-en-18-carboxylates. Reactant involved in: • Cyclization for the synthesis of β-carbolines • Synthesis of photochromic molecules with improved fatigue resistances and dark form stabilities • Asymmetric hydrogenation of acylsuccinate followed by lactonization for synthesis of oxotetrahydrofurancarboxylates • Amidation for synthesis of amino-acid derivatives of dihydropyranocoumarins Packaging 100, 500 g in glass bottle
