Some common heterocyclic compound, 675109-26-9, name is 6-Bromoisoindolin-1-one, molecular formula is C8H6BrNO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. category: indolines-derivatives
A mixture of 6-bromoisoindolin-1-one (2.0 g, 9.44 mmol), bis(pinacolato)diboron (2.41 g, 9.7 mmol), KOAc (1.86 g, 18.66 mmol) and Pd(dppf)2C12 (0.39 g, 0.49 mmol) in dioxane (50 mE) was stirred at 1000 C. overnight under a nitrogen atmosphere. The mixture was poured into water and extracted with EtOAc (100 mLx3). The combined organic fractions were washed with brine, dried over sodium sulfate and concentrated under vacuum. The residue was purified by chromatography on silica gel (1/10 to 1/5 EtOAc in pet. ether) to give compound 13A (600 mg, 25% yield) as a white solid. ESI mlz 260.0 [M+1].
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 675109-26-9, its application will become more common.
