These common heterocyclic compound, 222036-66-0, name is 5-Aminoisoindolin-1-one, its 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
The 5-amino-isoindoline-one (Intermediate 8a, 2.1g, 14.2mmoL), acetone (3.5mL, 47.6mmoL) and sodium cyanide (2.1g, 46.8mmoL) was added to 90percent acetic acid (45mL) in.The addition was complete, stirred at room temperature for 48 hours.To the reaction mixture was added water (50mL) and ethyl acetate (100 mL), separated, the organic phase was washed with water (3 × 50 mL), saturated sodium bicarbonate (50 mL), water (50mL), dried over anhydrous magnesium sulfate , filtered, and the solvent was distilled off under reduced pressure, the residue was purified by flash column chromatography, eluent PE: EA = 1: 1, to give a white solid 2.7g, 88percent yield.
The synthetic route of 5-Aminoisoindolin-1-one has been constantly updated, and we look forward to future research findings.
