107516-75-6, Diethyl 1H-indole-2,6-dicarboxylate is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 2: Synthesis of diethyl l-{3-[(tert-butoxycarbonyl)amino]-2,2-dimethylpropyl}- 1H-indole-2,6-dicarboxylate To a solution of diethyl 1H-indole-2,6-dicarboxylate (25.3 g, 97 mmol), tert-butyl (3- hydroxy-2,2-dimethylpropyl)carbamate (19.7, 97 mmol) and triphenylphosphine (50.9 g, 194 mmol) in THF (200 mL) is added and diisopropyl azodicarboxylate (40.2 mL, 194 mmol). The mixture is stirred for 60 h at room temperature and then the solvent is removed. The residue is separated into two portions and each of them is filtered through a short plug of silica gel (400 g) using 20% EtOAc in heptane. A mixture of diethyl l-{3- [(tert-butoxycarbonyl)amino]-2,2-dimethylpropyl}-1H-indole-2,6-dicarboxylate and diethyl 1H-indole-2,6-dicarboxylate (55 g) is obtained and the mixture is used in the next step without further purification.
107516-75-6, The synthetic route of 107516-75-6 has been constantly updated, and we look forward to future research findings.
