201940-08-1, name is tert-Butyl 5-bromoisoindoline-2-carboxylate, belongs to indolines-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. category: indolines-derivatives
To solution of the aryl bromide (0.200 g, 0.67 mmol) and Pd (PPh3) 4 (39 mg, 0.33 mmol) dissolved in THF under N2 was cannulated the crude vinyl zinc species from step A. The reaction was heated at 50C for 36 hours, and the then filtered through a plug of A1203 with aid of EtOAc and concentrated to give an oil which was used without further purification
The synthetic route of 201940-08-1 has been constantly updated, and we look forward to future research findings.
